Rental of anechoic chamber, semi-anechoic chamber, and reverberation room.

We have established an anechoic chamber with top-level performance in Japan.
Specialized staff in sound and vibration will respond.
Not only do we offer rental of the audio experiment laboratory, but we also provide equipment rental upon request, as well as contracted measurements conducted by our specialized staff.

example of use: Microphone/speaker characteristics measurement
Recording of dry source sound, sound source exploration by SI method, etc.

effective dimensions: 7.0 (W) × 7.4 (D) × 6.5* (H) m (* distance between sound-absorbing materials)
Height from piano wire to ceiling sound-absorbing material: 4.7 m

indoor dark noise: NC-15 or less (A-weighted sound pressure level: below 0dB)

inverse square law: 31.5 Hz ～ 10 kHz (1/3 octave band): 4 m
※JIS Z 8732(2000) Appendix Table A.1

sound-absorbing layer: 1.7 m wedge-shaped

example of use: Measurement of various noise levels
Measurement of acoustic power levels of office equipment and PC-related devices

effective dimensions: 8.2 (W) × 7.9 (D) × 5.4 (H) m

indoor dark noise: Less than NC-15 (A-weighted sound pressure level: 5 dB or below)

inverse square law: 100 Hz ～ 10 kHz (1/3 octave band): 4 m
※JIS Z 8732(2000) Appendix Table A.1

sound-absorbing layer: 400 mm flat plate + air layer

example of use: Reverberation room method sound power level measurement
Reverberation room method sound absorption rate measurement, sound transmission loss measurement, etc.

effective dimensions: Sound source room: 6.5 (W) × 8.3 (D) × 5.3 (H) m
Receiving room: 6.7 (W) × 8.4 (D) × 5.4 (H) m

reverberation time: 125 Hz: 11.7 seconds
500 Hz: 9.7 seconds
2 kHz: 6.1 seconds
