How do we perform an (architectural) acoustic test?

Again, the movements are acoustically tested in six different positions.

All rooms are sound proof and an acoustic test has been performed.

On the whole, I am very pleased,” said Gergiev after the acoustic test.

The test fixture includes a test chamber, an acoustic source, a reference microphone, and an acoustic resistor.

Measurement of sound absorption adapted from DIN 52215

How do we perform an (architectural) acoustic test?

The sound pressure level of the test sound wave and the sound pressure waveform are displayed on a screen of a display unit.

The acoustic source is configured to produce sound waves in the test chamber.

An acoustic source transmits acoustic to an acoustic receiver along an acoustic path.

The first acoustic module includes a first acoustic driver and a first acoustic duct, for conducting acoustic energy from the first acoustic driver.

A second acoustic module includes a second acoustic driver and a second acoustic duct, for conducting acoustic energy from the acoustic driver.

5.4Conclusions about the Acoustical Restruction Test.

A microphone (26), disposed within the microphone retaining chamber has a first acoustic port (30) in an acoustic relationship with the first acoustic passage and a second acoustic port (32) in an acoustic relationship with the second acoustic passage.

An acoustic detector (212) detects the acoustic signal, and an acoustic signal analyzer (214) interprets the detected acoustic signal.
