ASA S1.8: Reference Quantities for Acoustical Levels
Abstract: The scope of this Standard includes reference quantities for commonly used levels in acoustics, electroacoustics, and mechanical vibrations.
The use of levels to describe acoustical quantities is not made mandatory by this Standard. Reference...

ASA S3.13: Mechanical Coupler for Measurement of Bone Vibrators
Abstract: This standard specifies requirements for mechanical couplers used for calibrating bone-conduction audi-meters and for making measurements on bone vibrators and bone-conduction hearing aids, in the frequency range from 125 ...
ASA S1.6: Preferred Frequencies, Frequency Levels, and Band Numbers for Acoustical Measurements
Abstract: For certain acoustical measurements, a constant frequency increment is a suitable spacing. More commonly, however, a constant-percentage increment is adopted and the frequencies then form a geometric series. This standard deals with the geometric...
ASA S3.5: Methods for Calculation of the Speech Intelligibility Index
Abstract: Intelligibility Index (SII), that is highly correlated with the intelligibility of speech under a variety of adverse listening conditions, such as noise masking, filtering, and reverberation. The SII is computed from acoustical measurements or estimates of speech...
ASA S12.6: Methods for Measuring the Real-Ear Attenuation of Hearing Protectors
Abstract: values (see ANSI/ASA S12.68), nor does it specify minimum performance values for hearing protectors, or address comfort or wearability features....
ASA S3.2: Method for Measuring the Intelligibility of Speech over Communication Systems
Abstract: The scope of this standard includes the measurement of the intelligibility of speech over entire communication systems and the evaluation of the contributions of elements of speech communication systems. The scope also ...
ASA S1.13: Measurement of Sound Pressure Levels in Ai
Abstract: This standard specifies requirements and procedures for the measurement of sound pressure levels in air. These requirements and procedures apply primarily to measurements performed under normal, relatively quiescent ...
ASA S3.7: METHOD FOR COUPLER CALIBRATION OF EARPHONES
Abstract: calibration of earphones is to provide a simple, convenient, and reproducible means of determining the earphone's acoustical output. Each of the couplers described in this standard has been designed for use with a specific class of earphones. When so used...
ASA S3.1: Maximum Permissible Ambient Noise Levels for Audiometric Test Rooms
Abstract: , and manufacturers so that they can plan and construct appropriate acoustical treatment for the reduction of ambient noise in audiometric test rooms....
ASA S1.15 PART 2: Measurement Microphones – Part 2: Primary Method for Pressure Calibration of Laboratory Standard Microphones by the Reciprocity Technique
Abstract: This standard
