Title

Sound system equipment – Loudspeakers - Acoustical (Output based) measurements

Scope

This International Standard applies to passive and active sound systems such as loudspeakers, headphones, TV-sets, multi-media devices, personal portable audio devices, automotive sound systems and professional equipment. The device under test (DUT) may be comprised of electrical components performing analogue and digital signal processing prior to the passive actuators performing a transduction of the electrical input into an acoustical output signal. The standard describes only physical measurements which assess the transfer behaviour of the DUT between an arbitrary analogue or digital input signal and the acoustical output at any point in the near and far field of the system. This includes operating the DUT in both the small and large signal domains. The influence of the acoustical boundary conditions of the target application (e.g. car interior) can also be considered in the physical evaluation of the sound system. The standard does not assess the perception and cognitive evaluation of the reproduced sound and the impact of perceived sound quality.

Microspeakers

Scope

This International Standard applies to micro-speakers used in portable electronic devices. Usually, the size of the vibration area is not greater than 40 mm. This also applies to loudspeaker systems (known as "box"), which consist of one or more loudspeaker drive units provided with an enclosure. This standard provides the characteristics of micro-speakers that need to be specified as well as the relevant methods of measurement for micro-speakers that use sinusoidal signals, or noise, or impulsive signals. The main characteristics include, but are not limited to, impedance, amplitude frequency response, distortion, and power handling.
