New Guide for reproducible low-frequency acoustical measurements in reverberation rooms

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.

Keywords

low frequency; reverberation; modally dense sound field

Rationale

In most of the reverberation rooms used for sound measurement today, the sound field is not modally dense at the some of the low-frequency OTO bands where we make our measurements. Due to this, the lab-to-lab reproducibility of these test methods is poor. With the proposed method, the low-frequency measurements can be made reproducible.

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