Impedance tube designed and suggested for a range of 50Hz to 8KHz (first of its kind). It is used for determining the Noise absorption coefficient and Noise transmission coefficient of different materials manufactured by our client. The product was designed in total accordance with international, American and Japanese industrial standards.
Our impedance tube testing system is based on transfer function method which is much faster than the commonly used standing wave ratio method. The transfer function method separates the incident & reflected energy from the measured transfer function& then estimates the acoustic properties of the tested sample located at the end of tube.
We offer the complete set of impedance tube system which includes the tube, microphones, and DAQ hardware & measurement software.
Testing Type - Sound absorption, sound transmission loss & acoustic impedance.
Frequency range – 63-6300 Hz
