IASCA Testing

[Invisible]

Someone told me that when the doing the SPL testing it is done at a specific frequency, which is 100Hz. Could any one clarify?

Thanks

what u probably heard was that the meter only registers sounds from a 100hz and under (mostly bass notes)

Thanks for the clarification.

the meter recognises frequencies below 80hz and above 20 hz ..

ur car resonates at a specific frequency and to find that u have to do alot of testing
