Enhanced audiometry methods and instruments to provide assessments of the nature and / or extent of a subject's hearing loss or impairments. Embodiments include applying at least first and second different test electrical stimulations to a subject, wherein the first and second test electrical stimulations are configured to stimulate hearing perception in the subject and are different. An identification of one or more characteristics of the perceived hearing produced by the at least first and second test electrical stimulations, such as an origin location of the perceived hearing, is received from the subject, and recorded in association with the at least first and second test electrical stimulations. Clinicians may improve the efficacy of treatments for the hearing impairments based on the recorded information.

Providing technology to assist in attaching the equipment used for measurement to the subject and arranging it in the measurement room. [Solution] The display unit 13 displays a diagram from the examiner's perspective showing the type of equipment used for measurement, the correct way to attach it to the subject, and the correct way to arrange it in the measurement room. In air conduction and bone conduction measurements (Figure 3), a schematic diagram of the subject's head viewed from the front is placed in the center, and the equipment, represented by a figure that mimics the actual device, is shown attached to the head. The equipment for the right ear is shown in red, and the equipment for the left ear is shown in blue. In addition, in sound field measurements, infant hearing tests, and speech sound measurements under noise (Figure 4), a schematic diagram of the subject's head viewed from above is placed in the center, and in addition to the equipment attached to the subject, the speaker is displayed in a manner that allows identification of the type of sound presented, and the positional relationship between the speaker and the subject is clearly indicated. The examiner can compare the subject, the room, and the display unit 13 to confirm whether the type of equipment used and its attachment / arrangement are appropriate.

A neck-based personal attenuation rating (PAR) system is used for determining a personal attenuation rating (PAR) of a hearing protection device on a listener. Headphones with an audiometer are placed around ears of the listener, and the audiometer is operated to measure an on-ear hearing threshold of the listener without the hearing protection device. The headphones with the audiometer may then be placed around a neck of the listener, and the audiometer is operated to measure an on-neck hearing threshold of the listener with the hearing protection device. A neck-to-ear transfer function is applied to a difference in the measured on-ear and on-neck hearing thresholds to determine a measured personal attenuation rating of the hearing protection device. A determination is made on if an ambient noise level in an area surrounding the listener compromised the measured personal attenuation rating. This determines if the measured PAR is reliable.
