Application examples of abnormal sound inspection devices: Abnormal sound inspection of speakers.

We will introduce a case where automatic inspection was made possible by applying an abnormal sound inspection device!

Our "Abnormal Sound Inspection Device" utilizes an inspection algorithm based on the Maharano Vista Guchi method to automatically and quantitatively inspect the quality of sounds and vibrations. Here, we introduce a case where the "Abnormal Sound Inspection Device" was applied to the inspection of abnormal sounds in speakers. Traditionally, the presence of abnormal sounds was determined by the auditory perception of the operator. In this case, automatic inspection was achieved by playing inspection sounds from the abnormal sound inspection device to a wireless speaker. [Case Study] ■ Challenge - Previously, there was variability in determination due to inspections based on the operator's auditory perception. ■ Application Results - By using DSVI-MA, automatic detection of abnormal sounds was achieved with a microphone or accelerometer. *For more details, please refer to the PDF document or feel free to contact us.
