Comments on standards Comments for revision of IEEE Standards documents are welcome from any interested party, regardless of membership affiliation with IEEE. However, IEEE does not provide consulting information or advice pertaining to I

Since IEEE standards represent a consensus of concerned interests, it is important that any responses to comments and questions also receiv

For this reason, IEEE and the members of its societies and Standards Coordinating Committees are not able to provide an instant response to comments or questions except in those cases where the matter has previously been addressed.

Overview 1.1 Scope This standard provides the data, techniques, and rationale for translating head and torso simulator measurements from the eardrum to other acoust

44、ic reference points, such as the free field and the diffuse field. It applies primarily to measurements of devices that contact the ear, such as headsets and handsets. It can also be used for devices that do not contact the ear, such as speakerphones and wearable devices. It is applicable to communi

45、cation and multimedia audio devices over the frequency range of 20 Hz to 20 kHz 1.2 Purpose Common acoustic reference points are needed for comparing electroacoustic performance of handsets, headsets, speakerphones and other kinds of communication devices. It is also needed for comparing communicati

46、on devices with other devices such as loudspeakers, multimedia terminals and consumer audio equipment. The free field and diffuse field are appropriate reference points because the results relate closely to what we hear. For measurements on communication devices, the free field or diffuse field are

47、more widely applicable reference points than the legacy ear reference point (ERP). 1.3 How to use this standard When reading this standard for the first time, it is helpful to begin with Clause 4 and read the remainder of the document. When applying the standard, go to the applicable clause and use

48、the tables as instructed. 2.
