The scope of the SC-03-12 Working Group on Forensic Audio includes methods for the evaluation of audio material for authenticity and for preparation of audio material for clarity when used as evidence for argument or litigation.
The scope of the SC-04 Subcommittee on Acoustics includes the electroacoustic transduction of audio signals that are used in professional audio recording, reinforcement, and reproduction applications, the airborne propagation of such signals, and the measurement of such signals.
The scope of the SC-04-03 Working Group on Loudspeaker Modeling and Measurement includes the specification, modeling, and measurement of the electromechanical and free-field radiation characteristics of loudspeakers, individually and in arrays, intended for propagation of audio signals within the scope of SC-04.
The scope of the SC-04-04 Working Group on Microphone Characteristics includes the specification, measurement, and description of the pressure and pressure gradient transduction characteristics in amplitude, time, phase, and spatial domains of microphones intended for the reception of audio signals within the scope of SC-04, individually and in arrays, with and without accessory response-modifying devices, and the interface, environmental, and compatibility characteristics of such microphones.
The scope of the SC-04-08 Working group on Measurement and Equalization of Sound Systems in Rooms includes the description, specification, measurement, and calibration of electroacoustic sound systems in rooms and the characteristics of sound presented to an audience.
This effort identifies practices for estimation of annoyance of man-made sounds in the presence of background sounds, for automotive/aircraft, consumer, professional and land use planning applications. It includes intentionally generated sounds such as music and sporting events, and unintentional sound such as transportation system noise. It is to include auditory masking, not only integrated sound pressure. It considers relative disturbance but does not set thresholds for acceptability. It does not consider health impacts of sound.
The scope of the SC-05 Subcommittee on Interconnections shall include the usage, description, and designation of connectors for professional audio recording, reproduction, and reinforcement; and the wiring among such connectors and the circuits to which they connect.
It shall include the measurement of noise and interference produced by such interconnections and the polarities of analog audio transmitters, transducers, receivers, and wiring so interconnected. It shall also include the description of such interconnections. Such specifications shall be based, when applicable to their respective scopes, on the recommendations of other AESSC subcommittees. The scope of SC-05 shall not include the electrical characteristics of data interfaces and networks or the organization of the data structures therein. Its IEC liaison is SC 100C WG7.
The scope of the SC-05-02 Working Group on Audio Connectors shall include, within the bounds of the scope of SC-05, new usage, description, and contact designation for connectors for audio and ancillary functions.
The scope of the SC-05-05 Working Group on Grounding and Electromagnetic Compatibility Practices shall include, within the bounds of the scope of SC-05, all practices affecting usage and performance of audio hardware, with respect to the susceptibility of the signals it carries to effects such as noise and cross-talk due to the manner of its connection and construction, and the effects of its signals on other hardware and systems in its vicinity. It shall not set standards for personal safety with regard to such connections and construction, but shall keep safety considerations in mind in its recommendations.
