We Serve Companies that want to Improve Product Quality and Reduce Warranty Costs by

• Improving noise related quality control
• Identifying Defects through noise signatures

By Providing

• Custom software for in-line testing which eliminates background noise and provides a cost effective alternative to an acoustic enclosure

Noise Quality Control Testing in the presence of background noise provides a cost effective way to pass/fail noisy products

Advantages

• No need for an enclosure
• Fast test cycle times
• SPL spectra of direct sound from a target
• Suitable for low signal to noise ratios (up to S/N = -20dB)
• Few microphones
• Ability to detect defect signatures

Requirements

• 'Training' with respect to a 'good product'
• 'Training' with respect to ambient noise levels
• 'Training' with respect to defect signatures (if required)

Our system works analogous to a trainable voice recognition system where training is not required but desirable. Training only improves the accuracy of the system. Training is required if certain defects are to be identified.

The screenshot below shows a comparison of sound pressure level spectra for sound measured from an object in the presense of background noise (Measured), sound measured in an anechoic chamber (Baseline) and the signal after denoising by SenQC (Denoised).
