  • Study of Acoustic Material


    Performance study of acoustic material is crucial to sound-isolated box\'s design and manufacture. Acoustic performance(sound isolation, absorption and reflection) research of different materials can help to data acquisition for database as reference of sound-isolated box\'s design.
  • Acoustic Sound-isolated Box


    PRM can specially provide a steady testing environment with noise floor low as 20dBA for performance testing of acoustic products, such as speaker, receiver and mic. Sound isolation can reach more than 40dB(300Hz~20kHz), Also, we can customize sound-isolated box with special size and fixture, and provide integrated testing system solutions.
