T/SDIE 20-2024 The measurement method for audio performance of virtual reality devices
Basic Information
Scope
Main technical content: This standard describes the measurement conditions and testing methods for the acoustic performance of virtual reality devices, including two scenarios: music playback and voice calls. The music playback scenario includes tests for latency, maximum sound pressure level, frequency response, total harmonic distortion, background noise, fan noise, crosstalk attenuation, and sound attenuation, as well as related test conditions and analysis methods. The voice call scenario includes tests for latency, frequency response, loudness, background noise, distortion, voice quality, echo, simultaneous speaking, call noise reduction quality, and voice attenuation in different network transmission directions, both for receiving and transmitting. This standard is applicable to the research, development, design, and testing of acoustic systems for virtual reality products.
