This study investigated the potential and limitations of a self-fit hearing aid. This can be used in the “developing” world or in countries with large distances between the hearing-impaired subjects and the professional. It contains an on-board tone generator for in situ user-controlled, automated audiometry, and other tests for hearing aid fitting. Twenty subjects with mild hearing losses were involved. In situ audiometry showed a test-retest reliability (SD <3.7 dB) that compared well with the precision of diagnostic audiometry using headphones. There was good correspondence (SD <5.2 dB) with traditional pure-tone audiometry. In situ loudness scaling yielded important information about suprathreshold perception, which will have an added value for the selection of compression and the selection of maximum power output to be allowed in hearing aids.

“…In those envi ronments, in-situ audiometry may offer cost-and time saving potential (O'Brien et al, 2010;Keidser et al, 2011;Nesgaard Pedersen, 2011). In-situ audiometry has also been suggested for self-fitting hearings aids (Convery et al, 2011;Wong, 2011). When thresholds are measured through the earmold that will be used for the final fitting, in-situ audiometry can take the effects of the individual acoustic coupling into account, such as venting, residual ear canal volume, insertion loss, and middle ear impedance (Ludvigsen and Topholm, 1997;Ludvigsen and Kuk, 2001).…”

A Comparison of Conventional and In-Situ Audiometry on Participants with Varying Levels of Sensorineural Hearing Loss

et al. 2015

Differences between conventional PTA and in-situ threshold levels may be attributed to (1) frequency, (2) device/hearing loss, and (3) calibration/manufacturer effects. Frequency effects primarily resulting in an overestimation of hearing loss by in-situ audiometry in the low and mid frequencies are mainly due to sound drain-off through vents and leaks. Device/hearing loss effects may be due to leakage as well as boundary effects because in-situ audiometry is confined to a limited measurement range. Finally, different calibration approaches may result in different offset levels between PTA and in-situ audiometry calibration. In some cases, the observed threshold differences of up to 10-15 dB may translate to varied hearing aid fittings for the same user depending on how hearing threshold levels were measured.

“…Research on self-fitting has generally followed the clinical pattern of threshold-based prescription followed by finetuning (Convery, Keidser, Seeto, Yeend, & Freeston, 2015;Keidser & Convery, 2016;Keidser, Dillon, Zhou, & Carter, 2011;Keissling et al, 2015;Wong, 2012). In the present study, however, we bypassed individual prescription and gave participants the opportunity to make changes from a generic starting condition.…”

Purpose The purpose of the current study was to evaluate user reactions to custom software designed for self-adjustment of amplification. Method “Goldilocks” software was developed to allow user exploration and selection of preferred levels of overall output, low-frequency cut, and high-frequency boost while listening to preprocessed speech. Thirteen hearing-aid users and 13 nonusers self-adjusted before and after taking a speech perception test incorporated into the software. Results All 26 participants were able to complete the 2 adjustments and the intervening test in an average of 6.5 min—20 of them from on-screen instructions without experimenter help. Relative to a generic starting condition, the average participant opted to increase overall output, reduce low-frequency cut, and increase high-frequency boost. The first and second self-selected values were highly correlated, but there was evidence of further increases of overall volume and high-frequency boost after speech perception testing with the initial adjustment. There was no evidence that prior hearing-aid experience affected the ability to understand or complete the self-fitting process. Conclusions This approach to hearing-aid self-fitting can be a speedy, reliable, and feasible alternative to, or supplement to, conventional fitting procedures, but many questions remain to be answered.
