Optimal Choice for Communication Headset Performance Testing

As communication technology continues to evolve, the performance requirements for walkie-talkie headsets, as crucial components of communication devices, are becoming increasingly stringent. To ensure the headset's performance meets industry standards, various specialized testing equipment and methods have emerged. Among these, the Anechoic Chamber, also known as a "quiet room," plays a vital role in the field of communication equipment testing.

The Anechoic Chamber is a specially designed space with no surfaces that reflect sound waves, thereby eliminating or significantly reducing external ambient noise. As a dedicated environment for headset testing, the Anechoic Chamber provides a pure, non-reflective acoustic environment, allowing for accurate and reliable testing without interference from external noise. This ensures the accuracy of test results. Power Time takes pride in our professional and efficient Anechoic Chamber, which serves as an ideal testing environment.

Power Time Anechoic Chamber utilizes pyramidal acoustic foam as the primary sound-absorbing material. Its unique structure allows it to rapidly absorb sound upon impact, minimizing or eliminating echoes and noise, ensuring background noise levels as low as 35dB within the frequency range of 50Hz to 20kHz. This design meets the ISO3745-2003 and GB6882-2008 standards, providing robust assurance for precise testing of intercom headsets.

For precise testing, we employ the Danish GRAS artificial head as the testing hardware. GRAS is a globally renowned supplier of acoustic measurement equipment, and its artificial head, also known as a simulated human head or standard head, holds a pivotal position in the professional communication field. Its appearance and dimensions closely simulate those of a real human head, houses a precise transducer (microphone) internally to simulate the reception of sound by the human ear. Due to its highly realistic characteristics, the GRAS artificial head provides test conditions closely resembling real auditory environments.

In terms of software, we have chosen the Soundcheck 11.0 measurement system from the USA, which is acknowledged as the world’s standard in headset acoustic design simulation. This system greatly improves the efficiency and accuracy of R&D capability in measurement and analysis of harmonic distortion, vibrations, and noise.
