Audio Measurement Products
The System
SoundCheck System: The SoundCheck®system from Listen includes everything you need to perform audio measurements on a wide range of devices – the software, the audio interface, other test interfaces and accessories, and test sequences.
Software
- SoundCheck Software: The heart of the SoundCheck system – powerful software for all types of audio test.
Audio Testing Hardware
Audio Interfaces
Listen’s multi-function audio interfaces combine outstanding resolution and a low noise floor with a multitude of convenience features to streamline your audio test, such as built-in microphone power, exclusive software control, TEDS compatibility and more. Our range includes:
- AudioConnect 2: Our low-cost, portable interface is ideal for headphone testing and cost-sensitive production line applications. It features two inputs, two outputs and a headphone output. The USB connection to the computer also provides power, making it ideal for field applications.
- AmpConnect 621: The 6-in, 2-out interface is packed with functionality with 6 inputs, 2 line outputs and one amplifier output to power speakers and artificial mouths. Impedance measurement and digital I/O are also included. This interface is ideal for automotive applications with a 6 microphone array, speaker testing, and any measurement where an artificial mouth or speaker is needed, e.g. smart device testing.
- AudioConnect 8×8: Our newest 8-in, 8-out interface excels for high channel-count applications. Multiple units can be connected for synchronous expansion up to 32 input and output channels, and S/PIDIF I/O allows an additional two channels for mixed analog/digital signals.
Microphones, Power Supplies and Amplifiers
- SC Amp Audio Test Amplifier: SC Amp is the world’s only dedicated audio test amplifier, with features such as integrated impedance measurement, fixed gain to reduce calibration errors, and DC voltage offset support. It offers low distortion and a low noise floor.
- SoundConnect 2 microphone power supply: SoundConnect 2 is a TEDS compatible dual channel microphone power supply with low self-noise and a wide frequency response. It powers 2 SCM/electret or IEPE microphones or accelerometers, and is available with a 200V polarization option.
- SCM Audio Test Microphones: SCM Measurement microphones are robust, accurate, stable, and offer excellent directional response in both near and far field. They are available in 2 lengths.
Electronic Interfaces
- DC Connect: DC Connect enables measurement of current consumption of battery operated and other low voltage devices such as hearing aids
- MEMS microphone Interfaces: Interfaces for measuring and characterizing MEMS (Micro-Electro-Mechanical-Systems) microphones and other devices with a 1-bit PDM (Pulse Density Modulation) output.
- Bluetooth Interface: Interface which offers full control over all Bluetooth protocol settings and explicit control over the CODEC choice, sample rate, and transmitter power
Ancillary Components
- Impedance Box
- Footswitch
- Turntables
- Mouths, ears, couplers and head and torso simulators
- Production Line Test Chambers
- Calibrators
Noise & Vibration Measurement Products
Software
