Audio & Communication

Audio and communications acoustic testing plays a crucial role in the design and quality verification of modern electronic products. This is especially true for devices such as headphones, speakers, smartphones, TWS devices, laptops, conferencing systems, and automotive communications. Their user experience and core functionality are highly dependent on the accuracy and stability of their sound performance.

Major Scopes Of Testing:

• Microphone, speaker performance evaluation (i.e. AOP, FR, SNR, THD+N...)
• Audio algorithm performance evaluation (i.e. Beamforming, AEC, ANC, ENC, NS, NR...)
• Video conferencing duplex quality (i.e. Doubletalk, Echo Cancelling During Talk)
• Mobile phone calling sound quality (i.e. 3GPP Test)

Major Testing Items:

• Apple Car-Play
  • ITU-T P.1100, P.1110, P.1120
  • Siri
• 3GPP Test
• MOS Test
• Microphone Quality Evaluation
• Speaker Quality Evaluation
