Sound Headphone test troubleshooting
- If you can’t get a good test, it may be because the hearing aid may be muted.

- 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.

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.
