New Practice for Measurement of Sound Pressure Level Differences and Energy Decay Curves using the Impulse Response Method with Sweep Signals

1. Scope

The development of standards on the characteristics and performance of materials, products, systems and services relating to the acoustical environment and the promotion of related knowledge. The work of this Committee will be coordinated with other ASTM Committees and other organizations having mutual interest.


Impulse Response; Sweep;


The impulse response method using sweep signals is currently not allowed by any measurement standard, despite long-established and clear evidence that it provides superior performance compared to a measurement with noise signals. Other relevant standards (e.g. E90, E336, E2235, C423) can then reference this practice.

The title and scope are in draft form and are under development within this ASTM Committee.
