Acoustics. Audiometric test methods - Pure-tone air and bone conduction audiometry Ingestion-build-79769 Manufacturers of bitumen and bituminous1 Scope This part of ISO 8253 specifies procedures and requirements for pure tone air conduction and bone conduction threshold audiometry. For screening purposes, only pure tone air conduction audiometric test methods are specified. It is possible that the procedures are not appropriate for special populations, e. g. very young children. This part of ISO 8253 does not cover audiometric procedures to be carried out at levels above the hearing threshold
