ASA S3.36 – American National Standard Specification for a Manikin for Simulated in situ Airborne Acoustic Measurements

This standard describes a manikin which is intended to simulate the acoustical effects of a medianhuman adult, including diffractions affecting the in-situ performance of electroacoustic devices used onor near a person. The manikin consists of a head mounted on a torso that extends to the waist. Thehead is equipped with pinnae and ear simulators with acoustic impedance terminations andmicrophones located at positions corresponding to those of eardrums on a median human adult.Measurement results obtained with the manikin may differ substantially from similar results obtainedon an individual person due to anatomical variations. Median dimensions provided in the annexeswere drawn from the population samples described in the Bibliography.

The manikin is described by the acoustical performance requirements of this standard. Physicaldimensions of manikins that meet these requirements are provided for information but are not part ofthe standard. Dimensional information can be found in Annexes B, C and D.

For test application specific requirements, the user is referred to clause 8 for additional information,pertinent test standards, and/or any modifications to the basic specifications required for that particularapplication.

Manikins for binaural recording are outside the scope of this standard.
