Y-S3 General Operation

1.
•

Overview

Y-S3 is a software application that aids in speaker system design, using data entered by the user on room type and size, speaker
type, installation conditions, and amplifier and processor type and configuration to calculate the response from the audiences’
position. Y-S3 then presents the results as sound pressure distribution and contour figures for use in constructing appropriate
speaker systems.

Calculation

Atmospheric Condition
Enter “Humidity” and “Temperature”. These parameters affect the speed of sound and the air absorption coefficient. The default
settings are 50% for humidity and 20°C for temperature. Check the “Air Absorption” checkbox to take attenuation of high
frequency components due air absorption into account in calculations.

Yamaha Sound System Simulator Y-S3
Owner’s Manual

Precision
Select the degree of precision used in the SPL calculation and contour calculation respectively. When a lower precision is
selected, Y-S3 uses an interpolation for faster processing. You may use a lower precision in the design stage for faster processing
and the highest precision in the final stage for checking the detailed results.

Phase Consideration
Check the “Interference Sum” checkbox to take phase interference into account when calculating the frequency characteristics
and sound pressure distribution. Energy summing calculations are performed if you do NOT check this box.

Sound Source for Calculation
Select “Swept Band Noise” or “Full Band Noise” for use as the sound source in the calculation. When “Swept Band Noise” is
selected, band pass noise assumed to be used. The bandwidth corresponds to the frequency selected in Aspect View. In this mode,
the overall level in Graph is the average energy of each band response. When “Full Band Noise” is selected, full band noise is
assumed to be used. The overall level in Graph is the summation of each band response. The “Swept Band Noise” mode is
convenient when you want to see the frequency characteristic while referring to the required SPL. You may easily deduce the
overall SPL by averaging the SPL results at several frequencies in this “Swept Band Noise” mode. The “Full Band Noise” mode
is more reasonable for a comparison of the calculated SPL with the value measured by using full band pink noise and real time
spectrum analysis.

Graph Overall
Select the frequency range of overall level displayed in Graph. The default range is 20 Hz to 20 kHz. For “Swept Band Nose” (cf.
previous section), the overall level denotes the average level of the response in the selected range. For “Full Band Noise”, the
overall level equals the summation of the response in the selected range. Check “A Weighted” checkbox to process the sound in a
similar manner to that of the human ear, using “A” characteristics. The Overall figures in Graph are displayed in dBA units.

Peak Factor of Source Signal
Select the source type from “Sine (Peak-to-RMS 3dB)”, “Pink (Peak-to-RMS 6dB)”, or “Music (Peak-to-RMS 10dB)”. “Sine”
has a 3 dB difference between the peak signal and RMS, “Pink” has 6 dB and “Music” has 10 dB. In this list, you select a
peak-to-RMS level in a practical sense. These levels are used by the clip level indicator and for auto tuning. “Output

Others

Unit
Select “Imperial” (feet and Fahrenheit) or “Metric” (meter and Celsius) for units of length and temperature.

Listen
Enter the coordinates of the principal performer or person speaking. These figures should be absolute coordinates. You should
take height into account if you are using the equipment on a stage. For example, using a sound source 1.5 m for the stage floor,
when the height of the stage floor is 0.8 m from the ground gives a total height of 2.3 m. Y-S3 refers to the origin point when
creating auralization data. The auralization data is calculated using head-related transfer functions (HRTF) by assuming that the
listener is facing the Origin Point. See chapter 6 for how to create auralization data.

Contour Display
Check the “Wall” checkbox to show the walls in Aspect View. The height of the wall is fixed at 5 m. You may check any
unnecessary radiation onto the walls by checking the contour shown on the walls. Note that Y-S3 does not calculate the
reflections from the walls even if this option is selected.

Report Page Size
Set the size of the page to print. You can select letter size or A4 paper.

Placing Speakers
•

Overview

Place the speakers in the room. You can add positions for each speaker array on a conventional proscenium or stage, and place
speakers on flat surfaces within the room such as ceilings and walls.

•

Adding a new speaker (Add Speakers)

Click
in Speaker List or select [Add New Array] from the [Array] menu to open the Add Speakers window. You
can select the installation method (Enclosure type - Manual layout, Enclosure type - Auto layout, Distributed) from the list box.
Place each speaker array for which you have entered details. Installed speakers will be appear in Aspect View, and are available
for selection in Speaker List. See chapter 6 for details on calculation results.

Array Speakers
This is a very flexible installation method compatible with all Installation series speakers. You can save installation data for each
speaker array.
(See chapter 5)
Enclosure type - Manual layout:
The method allows a great deal of freedom in speaker layout, allowing the “Array Type” selection, mirroring, and direct entry of
coordinates.
Enclosure type - Auto layout:
Y-S3 will select an appropriate speaker array for your room and arrange them automatically, based on your “System Type”
selection.

Distributed Speakers
You can arrange speakers with a fixed spacing on a level surface (e.g. wall or ceiling). The compatible speakers for distributed
designing are the following Installation series speakers: IF2108, IF2208, IF2205, and S5, S15, S55 speakers. Since the speakers
will be treated as part of the flat surface, you cannot save this arrangement.
(See chapter 5)
Distributed:
Sets the parameters for the level surface in which speakers are placed, depending on your speaker and the “Plane Type”
selections.
Coverage:
Y-S3 automatically places speakers in the coverage area on the receiving surface, depending on your selections for placement
pattern and degree of consolidation of the receiving surface.
Grid:
You can place speakers at any intervals on a grid, based on your selections for placement pattern and the distance between
speakers.

Placing the speakers manually (Enclosure type - Manual layout)

Click
in Speaker List or select [Add New Array] from the [Array] menu to open the Add Speakers window.
Select “Enclosure type - Manual layout” from the list box. Select a speaker array type and enter the coordinates and conditions
for the area to calculate the results.

Name
Input a name for the new array (e.g. Center, Left, Right, Delays, etc). Y-S3 automatically assigns names for single speakers that
compose the array like ***sp1, ***sp2 (*** is the array name). You can change these names also in Speaker List after placing
the speaker array. To change them, select the speaker array or single speaker in Speaker List, right-click and select [Rename],
then enter the new name.

Array Type
Select the speaker array type from the list box. When you would like to use an array type which is not shown in the list box, you
need to import a speaker array template (“.ysd” file) from “ARRAY_LIBRARY” folder to the “Array Type” list. Select “Import
Array Type” from the list box and Y-S3 imports the data to the “Array Type” list so that you may select the array type in the list
box. The imported array type will remain on the list until you delete it, even after you restart the program. To delete the imported
data from the list, delete the “.ysd” file from the “data_folder∴template_folder∴SPA_DATA” folder in the program folder. Y-S3
requires at least one template to be present in the “Array Type” list. Placing an imported array template (.ysd) in the room will
convert it to array data (.spa) containing the conditions for the speaker array, which you can save and load. (See chapter 5)
The suffixes in the speaker array template have the following meanings.
p: Passive, b: Bi-amp, t: Tri-amp, r: rotate (horn-rotated), floor: +3dB (adding reverberations from the floor)
You can check the specifications for each speaker on the website at http://www.yamahaproaudio.com/.

Symmetry
Check this checkbox to place a mirror image of the speaker array with respect to the y-z plane. For a stereo system, when the left
side speaker is entered, the right side “mirrored” speaker will appear automatically. Speakers will overlap if Position x in “Array
Geometry” is set to the default (0.00). Please enter an appropriate figure. Note that since speaker figures are also mirrored, the
mirrored figure is different from the actual picture in some cases for some asymmetric models like IS2112AS or IF2115AS. This
will not affect calculation results. An asterisk (*) appears beside the array names of mirrored speakers, to help distinguish them

to finish without auto tuning. See chapter 5 for details about auto tuning.
You cannot use “Auto layout” in “SPL Mode” when Y-S3 displaying a sound pressure distribution. Always switch to “Array
Mode” or “Single Mode” before using this function. Additionally, “Auto layout” deletes any existing speaker arrays that have
already been placed and places new speaker arrays. Speakers placed suing the “Distributed” function are not deleted. This is
useful in instances such as when you want to replace speakers on a stage or proscenium but retain speakers installed in the
ceiling. The “Enclosure type - Auto layout” function does not execute for circular rooms or rooms that are too large, small, wide,
or narrow. In such cases Y-S3 displays an error message. Please use the “Enclosure type - Manual layout” function to position
speakers.

System Type
Select the speaker system type from the list box (Center, Center, LR, LCR, Side, Center + Side).

Ceiling Height
Enter the estimated ceiling height of the room. Y-S3 decides the array height referring to this parameter. The speaker arrays are
always set below the ceiling height. Note that Y-S3 does not estimate the reflection from the ceiling in the calculation.

Setting methods
The “Auto layout” function selects speakers that are appropriate for the shape, floor area, and proportions of the room. It also
takes the ceiling height you have entered into account when positioning speakers (Center, Center + Side, Side).The default angle
settings are; Pan and Rot: 0°, Tilt: 30, Splay Angle: minimum.

Coverage (Distributed Speaker Layout Pattern)
Speakers are placed automatically based on the coverage area of the receiving surface. This function is useful when evaluating
the speaker placement necessary to obtain direct distribution of sound.

Layout Judgment
Set the defining parameters for “Pattern”, “Bandwidth” and “Center Frequency” from the list boxes and choose a density.
Pattern:
Select either “Rectangular” or “Hexagonal” as a layout pattern for speakers on a flat surface.
Band Width, Center Frequency:
Set the bandwidth and frequency used to calculate the coverage area. Although the narrower bandwidths allow closer
distributions to the desired frequencies, they are also subject to more extreme distribution changes caused by interference and
other factors. The default setting is 2 Oct. Band, 1 kHz, which should cope with most vocal bandwidths
Density:
Set the density of the coverage area on the receiving surface. Take the distance between the receiving surface and the plane
where the speakers are located (the height, for speakers installed in the ceiling) when setting this parameter. Generally, higher
ceilings mean increased distances between speakers, so you should select high density to achieve sound pressure above a
constant level.

Speaker Arrangement

Y-S3 sets speaker parameters for each speaker array.
Y-S3 decides the speaker angles (Pan, Tilt and Splay Angle) to minimize the standard deviation of the sound pressure level
within the area that is selected by the user as the coverage of the speaker array.
When computing angles, the proper setting is selected from among the conditions in which all of the target points of the
speaker composing the speaker array are within the selected cover area.
Y-S3 decides the EQ and gain for each speaker so that the frequency responses are flat and their levels match the required
SPL set by the user at the target points of each speaker that composes the speaker array. (Note 1: In auto tuning, since sound
pressure level calculations at axis points are computed based on the summing of energy, peaks/dips from interference are not
corrected. Note 2: Delay is not tuned automatically. All the delays are set to 0 ms after auto tuning.)
In the level adjusting, Y-S3 first decides the necessary output power for each speaker referring to the required SPL. Then,
Y-S3 decides the attenuation level to adjust the necessary power difference between the speakers in one speaker array. Finally,
Y-S3 decides the input signal level from the necessary output power and amplifier gain.

Contour figure

Y-S3 displays the contour figure for -3 dB, -6 dB and -9 dB for the target point of the speaker array or component speaker
currently selected in Aspect View. The contour figure displays three lines indicating -3 dB (red), -6 dB(orange) and -9 dB(green)
drops in sound pressure from the target point. You can turn the display for each line on and off in from the [View] menu. These
figures are the bandwidth and center frequency figures selected in the list boxes in the upper area of Aspect View. When speakers
are mounted on the floor, the contour figure is not available when the target point is not located on the receiving surface or in an
enclosed space. Additionally, Y-S3 does not display target points or contours of speaker arrays placed using the “Symmetry”
function in “Enclosure type - Auto layout” and “Enclosure type - Manual layout”. To display contour figures for walls, open the
Project Properties window from the [File] menu, and place a check in the “Contour Display” checkbox in Others. Y-S3 does not
display a sound pressure distribution for walls. This wall is used for display the contour figure only, and is treated as being
acoustically transparent. Thus calculations to do take reflections from this wall into account.

Array Mode
Displays a contour figure for speakers displaying target points. A speaker array made up of a single speaker will have the same
display as “Single Mode”. Speakers distributed on a plane are treated as individual speakers, and thus have the same display as
“Single Mode”.

Single Mode
Displays a contour figure for each speaker displaying target points. When you have placed multiple speakers, you can use the
checkboxes in Speaker List to turn each speaker on/off. Since the contour figures for each speaker are calculated relative to the
respective target points, the SPL for each speaker will be different even for contour lines of the same color.

10. General Theory
General calculation methods

Y-S3 computes the speaker array response at the receiving point or audience area.
The responses are computed by combining the responses from each speaker based on a geometrical simulation.
Each speaker response is computed using measured directional impulse responses. First by selecting the impulse response
for the corresponding direction based on the relationship between the receiver point and the speaker position, and then
considering the effects of attenuation by distance, air absorption, amplifier type, system attenuation, and processor settings
(EQ, delay).
There are two methods of combining responses: a method that considers the interference and a method that is based on the
summing of energy and not taking the interference into account.
The response is limited to direct sound. Calculations are performed as for a free sound field without any reflections.
The sound pressure level is calculated assuming sine wave or pink noise input to the system.
There are two types of pink noise: band-pass filtered noise for the “Swept Band Noise” option or overall noise for the “Full
Band Noise” option.
The response for the two channels used in auralization is computed by first convolving the head-related transfer function
(HRTF) of the directions corresponding to each speaker’s response, and then combining these responses.

Auto setting methods
•
•

There are two auto setting functions. “Auto layout” selects the appropriate speakers for the current room configuration, and
“Auto tuning” determines the parameters (Angle, EQ, Amp type, Input Level and Attenuation) for each speaker.
The results for each function are only rough estimates, and adjustments or modifications will be necessary for either method.
Calculations are made based on the following theory.

1. Auto layout
• Y-S3 selects the speaker type that is appropriate for the configuration of the room, its area, and the dimensions of the floor.
• Speaker positioning is conducted in accordance with the speaker arrangement methods (Center, Center + Side, Side) while
considering the ceiling height of the room.
• Angles are set to default: Pan and Rot = 0 degrees, Tilt = 30 degrees and Splay Angle = minimum.
2. Auto tuning
• Y-S3 sets speaker parameters for each speaker array.
• Y-S3 decides the speaker angles (Pan, Tilt and Splay Angle) to minimize the standard deviation of the sound pressure level
within the area that is selected by the user as the coverage of the speaker array.
• When computing angles, the proper setting is selected from among the conditions in which all of the target points of the
speaker composing the speaker array are within the selected cover area.
• Y-S3 decides the EQ and gain for each speaker so that the frequency responses are flat and their levels match the required
SPL set by the user at the target points of each speaker that composes the speaker array. (Note 1: In auto tuning, since sound
pressure level calculations at axis points are computed based on the summing of energy, peaks/dips from interference are not
corrected. Note 2: Delay is not tuned automatically. All the delays are set to 0 ms after auto tuning.)
• In the level adjusting, Y-S3 first decides the necessary output power for each speaker referring to the required SPL. Then,
Y-S3 decides the attenuation level to adjust the necessary power difference between the speakers in one speaker array. Finally,
Y-S3 decides the input signal level from the necessary output power and amplifier gain.
