Scope: This working group coordinates ANSI projects with IEC working groups. It prepares revisions to existing earphone calibration standards, prepares new standards for circumaural earphones, and studies and prepares standards for simulation of the human ear for measurement purposes. It also maintains the ANSI standards for couplers, coupler measurements, and ear simulators. Currently these standards are
ANSI S3.7-1995 (R2008) American National Standard Method For Coupler Calibration of Earphones
ANSI S3.25-1989 (R2009) American National Standard Method For An Occluded Ear Simulator
