Summary:
|
Within the context of Safe-listening devices and systems, as described in H.870, accurate dosimetry readings require an understanding of the technical characteristics of the transducer responsible for delivering the sound to the user (cf. ITU-T H.870] Table II.2).
The accuracy of dosimetry may be limited in situations where the technical characteristics of the headphone/earphone is unknown to the device, therefore it would be advantageous for manufacturers of headphones and earphones to provide the appropriate technical information and to have a decentralized register, so that manufacturers of devices can utilize this information to calibrate their dosimetry mechanism.
