We know that you want a turnkey system, so we offer additional products of our own, and have teamed up with other suppliers to offer a wide range of additional test equipment to use with SoundCheck for a complete test solution. This additional audio test equipment includes:
Additional software
SoundMapTM: SoundMapTM, a Time-Frequency Analysis program, has many applications including 3D waterfall plots of loudspeaker and microphone impulse responses, loose particle detection in loudspeakers and analysis of dropouts in digital devices such as Bluetooth headsets and VoIP telephones.
Test Sequences - we offer a selection of pre-written test sequences for testing to industry standards. Many basic sequences are included in the software or may be downloaded from our website. Other more complex sequences, such as testing to TIA standards and hearing aid standards, can be purchased from Listen.
Hardware
Pro-Audio Sound Cards and Data Acquisition Devices: SoundCheck will work with any professional sound card or data acquisition card. We have partnered with several manufacturers to offer a range of stereo and multi-channel cards to meet all applications and budgets.
Measurement Microphones: Listen’s SCM measurement microphone is a robust, free-field microphone with a flat frequency response and high sensitivity. It is suitable for R&D or production line use. Listen can also supply measurement microphones from other manufacturers.
AmpConnectTM: Listen's NEW AmpConnect combines an impedance box, amplifier, microphone power supply and digital I/O card into one simple USB controlled piece of hardware. This low cost solution greatly simplifies loudspeaker, microspaker and microphone measurements.
Microphone Power Supplies: Listen’s SoundConnect can power SCM, B&K and G.R.A.S. measurement microphones and extends the dynamic range of your measurement system. It ensures good amplification linearity with a minimum of noise and distortion. Listen also offers microphone power supplies from other manufacturers including portable battery-operated units.
DC power supply and current monitor: Listen’s DC Connect™ is a USB controlled precision DC power supply and current monitor. It enables high resolution dynamic measurements of voltage and current consumption in portable electronic devices such as hearing aids, microphones, cell phones, PDAs and other battery powered electronic devices.
Amplifiers: Amplifiers are a critical part of many measurement configurations. Listen offers a selection of amplifiers that have been chosen for their high reliability, durability and excellent performance.
Other Test Fixtures: Listen can supply turntables, head and torso simulators, artificial ears, mouths, calibrators and other test fixtures from several test and measurement companies.
Production Line Accessories: Footswitches, cables and additional production accessories such as barcode scanners are also available from Listen.
Impedance Boxes: Listen offers an 0.25Ω impedance box for measuring the impedance of a loudspeaker.
