Wireless Devices (including bluetooth)
SoundCheck can carry out the same range of measurements on wireless devices as it can on their hard-wired counterparts, measuring many parameters including frequency response, phase, distortion and more.
- Frequency response
- Self-noise and signal-to-noise
- Distortion (Rub & Buzz /Perceptual Rub & Buzz
- Simulated free-field measurements
- Directional characteristics (polar plot)
- Impulse response
- Max SPL
Wireless and Bluetooth Testing
SoundCheck is the ideal tool for testing all kinds of wireless devices as it contains all the algorithms needed to compensate for issues such as time delay, enabling any speaker, headphone, or microphone to be measured exactly the same way as its hard-wired counterpart. For example, SoundCheck’s ‘record padding’ feature enables the test signal to be buffered to overcome any connection delay.
For Bluetooth testing, Listen offers the BTC-4148 bluetooth interface, which can be fully controlled from within SoundCheck. This interface offers full control over all Bluetooth protocol settings and explicit control over the CODEC choice, sample rate, and transmitter power, enabling devices to be specifically tested under the conditions that they need to operate.
Please see the application section for the wireless device that you need to test (e.g. headphones, speakers, microphones, etc.) for more specific information on the functionality of SoundCheck for measuring that specific device.
Examples: How do our Customers use SoundCheck for Measuring Wireless Devices?
These are just some of the loudspeaker measurements that our customers are making:
- R&D measurements of bluetooth speaker, measuring frequency response, phase and distortion
- Competitive evaluation of bluetooth headsets
- Measurement of speakers in a wireless home entertainment system
