Sound Headphone test troubleshooting

• If you can’t get a good test, it may be because the hearing aid may be muted.
• Tip: On some wired headphones, the muffler is located on the cable.
• The volume may be set to very low in the Sounds and Audio Devices Properties window in the Windows Control Panel.
  You may have a loose USB connector.
• In Windows XP, the Plantronics USB Audio device or headset is not selected as the default audio recording device.
• The “Use only preferred, or default device” box is not checked.

What kinds of tests will you do in the audio lab?

• UL will verify subsonic and ultrasonic (HD audio) performance demands by authenticating and evaluating quality measures.
• Such as frequency response, THD, signal-to-noise ratio, phase, crosstalk, sample rate, and bit depth capability.

How will you perform the audio test?

• To test HD audio quality, we run what we call an objective test.
• During this test, we put a headset on a head and torso simulator.
• The head and torso system measures the frequencies produced by the product.
• For the subjective test, we will form a panel of 30 consumers and five chosen industry professionals.
• Each participant must complete a questionnaire of approximately 40-50 questions while listening to different music types.
• We then produce a report for the manufacturer that shows the results and what people think about the headphones’ sound quality.
