100 Things #74: Easily Save Measurements in Any Format

SoundCheck offers flexible options for data processing, allowing measurement data to be saved in a variety of formats. For fast and reliable operation, saving data can be automated with autosave steps in a sequence. SoundCheck can save measurements to a .tdms file for including important metadata with your measurements, Excel for reporting test data and […]

100 Things #73: Active Speech Level Control in SoundCheck

SoundCheck’s incorporation of active speech level allows for stimulus to conform with telephony testing standards. This means testing to IEEE and TIA standards can be automated within a sequence, allowing an entire test to be run without operator intervention. Active speech level is incorporated directly into SoundCheck’s stimulus step, and becomes available when selecting dB […]

100 Things #72: Transient Distortion Analysis With enhanced Loose Particles

Listen’s enhanced Loose Particles algorithm measures transient distortion independently of harmonic distortion, with correlation to human hearing and offering high accuracy, easy perception, and fast analysis. eLP is ideal for identifying transient distortion in any environment, like identifying rattling buttons in audio devices, and automotive Buzz, Squeak and Rattle (BSR) measurements. SoundCheck sequences can quantify […]

100 Things #71: Calculating Thiele-Small Parameters of a Loudspeaker

SoundCheck can be used for loudspeaker design, performing measurements of loudspeaker performance in an enclosure, known as Thiele-Small parameters. SoundCheck includes three different methods for calculating Thiele-Small parameters: known mass, added mass, and known volume. Depending on what driver measurements are known and unknown, these three sequences provide options for all testing scenarios. Operator messages […]

100 Things #70: Make Smarter Tests with Sequence Logic

SoundCheck has sequence logic integration through every step. The ability to use If/Then logic with sequence steps means sequences expand beyond a linear path. Loops are easily created, perfect for using turntables to create polar plots. Incrementing and measuring level increases means it’s easy to automate testing devices to specific SPL, distortion, and perceptual distortion […]

100 Things #69: Testing MEMS Microphones In SoundCheck

Testing MEMS microphones and devices in SoundCheck is as simple as any microphone test. In fact, SoundCheck’s ability to work with different devices means MEMS setup is plug and play. Just like testing an analog microphone, SoundCheck can perform standard tests using microphone substitution or microphone subtraction. SoundCheck allows up to 64 channels of simultaneous […]

100 Things #68: Using Transfer Function to Measure Smart Devices

Modern devices are becoming better and better at filtering out unwanted background noise from calls. This includes noises like sine sweeps, typically used to test these devices. Instead testing these devices with real world signals like speech, music, and noise can bypass noise suppression. The ability to use transfer function in SoundCheck to test these […]

Introducing Enhanced Loose Particles (eLP)

Watch our launch seminar for Listen’s latest algorithm, enhanced Loose Particles (eLP). This new algorithm significantly improves production line transient distortion measurement. It offers high accuracy, easy correlation to human perception, and identifies transient distortion artifacts separately from harmonic distortion for easy troubleshooting. It’s also ideal for identifying rattling buttons in audio devices, and automotive […]

100 Things #67: Measuring Active and Passive Noise Cancellation for Hearing Protection

SoundCheck makes testing to standards simple by automating precise measurements into a single sequence. In this test sequence hearing protection devices can be tested to the ANSI S3.19-1974 standard to find their NRR rating. Sequences in SoundCheck make testing simple, with message steps instructing operators when interaction is needed with removing or placing hearing protection […]
