After the musicians had left the stage, we measured the reverberation time in the empty hall to be 2.9 s at 500 Hz, and estimated the reverberation time in a fully occupied hall at 2.4 s 500 Hz.
When the stage is set up with a stage curtain instead of the reflection panels, the reverberation time is 1.4 seconds when the hall is full.
In addition, our system's reverberation time measurements not only support conventional noise interrupting methods but also impulse response integration methods, standardized in ISO 354.
The reverberation time was measured at 1.9 seconds(unoccupied, at 500Hz), an unusually long reverberation time for a room with only 630 seats.
In the impulsive excitation method, Type 2250-S automatically measures reverberation time when a balloon burst or starter pistol is used to excite the room.
This includes occupational health and safety(OHS), building acoustics and reverberation time applications, infrasound(G-weighting) measurements, product development and quality control, and even sound power and intensity and noise source identification applications.
It is known that the reverberation time is almost constant in a concert hall, but the sound quality is quite different from the front seat and the rear seat. It is because the ratio of the direct and the reflective sound is different.
The main hall with 1,905 seats has optimum reverberation time and reception level for theater programs and classical music performance, and designed so that clarity of musical resonance is ensured, as well as to allow the sounds from the stage to seem as close-by as possible.
In classrooms, for example, a good speech intelligibility is hardly possible if the reverberation time is too long, whereas for a piano sonata in a concert hall, a longer reverberation time may be more effective for a pleasant acoustic sound.
Characteristics include using a life-size copy of the largest wall stone of Osaka Castle as the background of hashi-gakari(roofed passageway connecting the main stage to the backstage), and setting the reverberation time at 1 second to accommodate the qualities of music of noh.
To use the Tsukuda slide rule shown in Photo 1, one need merely slide the center bar of the slide rule, which has values of V/S, so that it aligns with the mark of V/S on the fixed portion of the scale, and the relation of the average sound absorption coefficient α and reverberation time RT values can be read.

Which plots reverberation times measured in Yamaha Hall.
At 500 Hz, the room's reverberation time is slightly longer than one second, and the high frequencies also reach about 0.9 seconds, reverberation times on a par with the average contemporary small hall.
This is affected massively by reverberation time, how reverberant a room is.
ISO 3382: Measurements of the reverberation time of rooms with reference to other acoustical parameters.
ISO 3382:1997, Acoustics- Measurement of the reverberation time of rooms with reference to other acoustical parameters.
Measurement of reverberation time is conducted to analyze the current sound field of the restaurant.
In case the decay curve is completely exponential, it is exactly the same value as the reverberation time.
Based on this measurement, we calculated the reverberation time in a fully occupied hall to be 1.9 seconds.
