General Operation

• 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.

• Startup

Double-click the Y-S3 icon on the desktop or select [Start] - [Programs] - [YAMAHA] - [Y-S3]. The program starts and

the main window appears.

Click in the main window to open a new project.

• Calculation

Yamaha Sound System Simulator Y-S

Owner’s Manual V3.1

19

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.

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.

Fig: Level difference between “Sound Source for Calculation” settings

Swept Band Noise Full Band Noise

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.
