DK-Technologies says its booklet, “Audio Levels and Readings,” offers answers to audio metering questions such as why engineers measure audio levels, use the dB scale or talk about Leq(m) and Dynamic Scales.

The booklet is written by independent audio consultant and AES member Eddy Bogh Brixen. It is supplied free to anyone who purchases an audio meter from DK-Technologies. It is available as a download from the company’s Web site.
