CCIR/ARM: A Practical Noise Measurement Method

Authors: Dolby, Ray; Robinson, David; Gundry, Kenneth J.

AES Convention 60 · Paper 1353 · May 1978

Abstract

In 1972 Dolby Laboratories investigated techniques for measuring noise in professional and consumer audio equipment. We needed a method giving agreement with subjective assessments for use within the company and for exchanging information with outside organizations such as licenses. Our study revealed that existing methods were unsatisfactory but that the use of the CCIR weighting characteristic with unity gain at 2kHz in conjunction with an average-responding meter (ordinary millivoltmeter) gave appropriate results. Practical details, circuitry, and applications are discussed.
