Acoustics

Overview:

A Hemi Anechoic chamber is an echo-free enclosure that is designed for acoustic analysis in a free-field environment. The unique wedge design provides an optimum level of sound absorption, for precise, repeatable acoustic measurements by allowing sound waves to propagate in all directions without any obstruction or reflection.

Our Capability:

TÜV Rheinland’s one-of-a-kind in-house Acoustic Test Laboratory at Andhra Pradesh MedTech Zone, Visakhapatnam performs precision and engineering-grade testing on a wide variety of devices ranging from handheld equipment to large machines including medical devices with alarm systems such as Ventilators, Incubators, Multi-parameter Monitors and many more.

The Hemi Anechoic Chamber in the Medical Device Centre of Excellence is the only such testing chamber in India established by an international certification body that is in compliance with ISO/IEC 17025 norms.

The chamber is designed to comply with ISO 3745 Standard. The primary use of this chamber is for determining Sound Power as per ISO 3744. Real-time analysis such as Time Signal, FFT, One-Third Octave are possible and A, C & Z-weighted sound pressure level and sound power level or sound energy can also be determined within this chamber.
