It can make simulated free-field measurements of basic output response and frequency response, which allows evaluation of loudspeakers in a normal reverberant environment, thus avoiding the need for an anechoic chamber.
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.
Room acoustics In a room, good acoustics require a design that is fit for purpose, such as easy communication and a high degree of intelligibility in office spaces or long reverberation times in concert halls.
Hypothesis 4- Because the reverberation is simple It is similar to hypothesis 3, but there is a possibility that the structure of the reverberation influences the ease of hearing rather than the amount of reverberation.
On 11 March 2012, one year after the disaster, I stood on the steps of the State Library of Victoria in Melbourne, feeling the reverberations of taiko drumming.
Producing friction effect, reduce noise, can be a lot of absorption of sound source, reduce the reverberation time, reduce indoor noise, achieve ideal effect of mute.
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.
大ホールの残響時間は舞台反射板設置の満席時1.8秒であり、舞台幕設置の満席時1.4秒である。
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.
残響時間は舞台反射板-舞台幕設置時、1.2-0.9秒(満席時、500Hz)である。
With the hall's acoustical panel system in place and the proscenium stage curtain, the hall's reverberation time measures 1.2 and 0.9 seconds with a full audience, at 500 Hz.
The reverberation time was measured at 1.9 seconds(unoccupied, at 500Hz), an unusually long reverberation time for a room with only 630 seats.
仮説3と似ていますが、残響の量ではなく、残響の構造が聴こえやすさに影響している可能性があります。
It is similar to hypothesis 3, but there is a possibility that the structure of the reverberation influences the ease of hearing rather than the amount of reverberation..
EVI Audio, the pro-audio division of Telex Communications, manufactured the sound system. They reported that the reverberation time was 4.9 seconds at 500 Hz, with empty seating.
For these, you need to measure the sound both inside and out, and to correct the difference for reverberation and background noise in the receiving 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.
Special reverberation rooms constructed to fulfil the requirements of ISO 3743-2, on the other hand, are less expensive and, since their methods provide engineering-grade results, particularly suitable for direct measurement of A-weighted sound-power levels of a series of small noise sources.
What is more important are the feelings risen, echoes of the dreams and paths that do not lead to anything or anywhere. when you draw a line you separate order from the disorder but you also call forth or invite something unexpected and restless to exist and to a visible form.
The hall is equipped with an acoustic reflector, reverberation variable curtain and movable proscenium, and can be used for various purposes such as music, theater, and dance.
