IEEE 1652-2016 pdf free.IEEE Standard for Translating Head and Torso Simulator Measurements from Eardrum to Other Acoustic Reference Points.
ear reference point (ERP): A virtual point for acoUstiC and geometric reference located outside the entrance to the ear canal. The exact location is specified for each type of ear simulator.
eardrum reference point (DRP): A point located at the end of the ear canal, corresponding to the eardrum position. Also known as the drum reference point.
free field complete definition (FF): (A) Sound field in a homogenous, isotropic medium free from boundaries. In practice, the effects of boundaries on a free field are negligible over the region of interest. () (Simple definition) Sounds field free of reflections.
frequency response: Electrical, acoustic, or electroacoustic nsitivity (output/inputL or gain, as a function of frequency.
head and torso simulator (HATS) for telephonometry: manikin incorporating a mouth simulator and car simulator(s), extending downward from the lop of the head to the waist, designed to simulate the sound pick-up characteristics and the acoustic diffraction produced by a median human adult and to reproduce the acoustic field generated by the human mouth.
receiver. An electroacoustic transducer that converts an electrical signal to sound and delivers it directly to the ear, sealed or unsealed.
speaker (also loudspeaker: An electroacoustic transducer that converts an electrical signal to sound and delivers it to the ear from a distance of several centimeters or greater.spectrum: A ditribution of amplitude (or phase, or some other quantity) as a function of frequency.It is often expressed in bands. Bands may be of constant percentage width, such as 1/3rd or 1/12th octave bands ( -23% and -6% of the center frequency, respectively). Bands may also be of fixed width,regardless of center frequency (e.g. 50 Hz). Instead of bands, a spectrum may also be expressed as spectrum density, which is equivalent to 1 Hz bands.IEEE 1652 pdf free download.
