Meyer Sound Introduces M-Noise Test Signal for ‘Real World’ Loudspeaker SPL Measurements

Meyer Sound has introduced M-Noise, a new test signal that will promote standardized measurement of a loudspeaker system’s maximum linear output. A mathematically derived test signal that effectively emulates the dynamic characteristics of music, according to Meyer Sound, M-Noise enables a far more accurate measurement of a loudspeaker system’s linear peak SPL in any application requiring reproduction of musical content.

VC Spotlight: CLIO Pocket User Report

In this article, Vance Dickason explores Audiomatica's CLIO Pocket analyzer. Rather than go into detail regarding all the measurement routines available in CLIO Pocket - audioXpress already published a thorough review in the October 2015 issue - Dickason gives practical examples using measurements for a couple of drivers in the same way he does for his monthly column, Test Bench. This article was originally published in Voice Coil, March 2016.

Target SPL and Required Amplifier Size

Target SPL and Required Amplifier Size

In a previous article (Loudspeaker Sensitivity: What’s a Watt Anyway? April 2010 Voice Coil), I examined the topic of loudspeaker sensitivity and how it may or may not relate to the overall sound pressure level (SPL) produced by a loudspeaker. The output capability of the amplifier driving the loudspeaker is of equal importance to achieving the target SPL from the direct field of a loudspeaker. This can also be related to the driving signal or the intended program material. This article was originally published in Voice Coil, May 2010.
