About ALT

We will take care of all your accredited acoustic and vibration calibration

ISO17025 accredited Acoustic Laboratory Thailand Co., Ltd. (ALT) is a fully independent acoustical laboratory based in Bangkok, Thailand.

We provide various calibration services for sound registration instruments and accessories such as microphones and calibrators as well as calibration services for accelerometers (onsite and in our laboratory).

All our experienced calibration engineers keep updated with changing ISO17025 and other standards.

In our acoustic laboratory in Bangkok, Thailand, we also perform material testing, either with an impedance tube or in our anechoic or reverberation rooms.

ISO17025 Accredited Acoustic Calibration, ILAC 24-LB0054 issued by the Ministry of Industry, Thai Industrial Standards Institute.

Acoustic Laboratory Thailand cooperated with the accredited Norsonic Calibration Laboratory in Norway and set up the ‘Norsonic Calibration Laboratory Asia’ in 2014 in cooperation with Geonoise Thailand.

As there is an increased need for independent acoustic calibration as well as acoustic material testing a new independent company has been founded, Acoustic Laboratory (Thailand) Co., Ltd. which is accredited by the Ministry of Industry (ILAC24-LB0054) to perform calibrations following ISO17025.

Our acoustic laboratory can calibrate any brand of microphones, sound calibrators, sound measuring instruments, DAQ’s, vibration meters and accelerometers to us for calibration whenever needed.

Calibration contracts are available to ensure calibration on regular basis.

Acoustic material testing can be performed with our impedance tube (Kundt’s tube) or in the decoupled reverberation rooms. STC values up to 70 dB can be accurately measured. (transmission loss)

In the reverberation rooms, we can also perform sound absorption measurements complying with ISO354.

Sound power measurements complying with ISO3744 and ISO3745 can be performed in our acoustic rooms. RSS (Reference Sound Source) calibration is also available.

Acoustic Laboratory Thailand (ALT) can perform almost any acoustic and vibration research. Any methodologies, certifications, accreditations, licenses can be applied such as ASTM, ISO, ANSI, SAE, JIS etc.
