m+p Impedance Tube Solutions

Sound quality is becoming increasingly important in product design. Constructive measures and acoustic materials serve to reduce or optimize the perceived noise of a product in the context of sound design. The sound characteristics of such materials can be identified with impedance tubes in the laboratory under controlled conditions.

With the optional Impedance Tube Testing software package, m+p Analyzer allows the calculation of important characteristics of acoustic materials such as absorption coefficient, reflection coefficient, impedance and transmission loss coefficients based on impedance tube measurements according to ISO 10534-2, ASTM E1050-12 or ASTM E2611-17.
