Anechoic chamber for car air conditioning

We can conduct noise measurements inside and outside the vehicle under conditions close to actual driving conditions!

The "Car Air Conditioning Anechoic Chamber" is an evaluation testing room for car noise, vibration, and unpleasant sounds. This chamber is used for measuring the noise of car air conditioning systems in actual vehicles, allowing for noise measurements inside and outside the car under conditions close to real driving situations by managing indoor temperature, humidity, and wind speed, temperature, and humidity using a front wind speed device. Additionally, a compressor drive unit (with variable speed and a three-dimensional positioning device) stored in the pit under the chamber allows the car air conditioning system to operate even when the engine is off, enabling noise measurements of the air conditioning unit without interference from engine noise. 【Features】 - Sound insulation provided by a concrete structure, and the interior is lined with sound-absorbing materials. The soundproofing of circulating air is achieved through low-speed ducts and silencers. - The solar radiation device installed in the ceiling uses metal halide lamps with spectral energy distribution characteristics that meet EPA standards. *For more details, please download the PDF or feel free to contact us.
