Summary

Hearing speech in the presence of background noise is a significant challenge for those with hearing loss. Being able to hear speech in noise has been rated as the most sought-after feature in hearing aids by hearing aid users. Our study aims to evaluate the effects of adaptation to hearing test in noise on speech perception, spatial perception and satisfaction in bilateral hearing aid users. The development process of speech understanding in noise in individuals with hearing loss over the age of 50 will be monitored with ACT and ecological-HINT tests. Spatial perception will be assessed with the Speech, Spatial Perception and Hearing Quality (SHRQ) Scale, which is a scale that evaluates the current hearing quality in adults. The hearing aid satisfaction process of the participants will be assessed with the APHAB survey.

Interventions

DIAGNOSTIC_TEST

ACT method in fitting

The ACT diagnostic test is a suprathreshold, non-language-specific test that measures an individual's hearing ability in real-world noisy environments to determine the level of assistance needed in noise. The test uses the audiogram shape and levels to ensure the correct stimulus intensity is applied. The ACT test then uses the patient's audiogram to present a suprathreshold stimulus (a siren-like sound) to objectively map their hearing ability in noisy environments. In other words, the audiogram measures quantity, i.e. hearing ability, while the ACT measures the quality of hearing. This makes the ACT a robust assessment that reflects an individual's real-world hearing abilities.

DIAGNOSTIC_TEST

Traditional fitting

The control group will be fitted with traditional fittings, and the results will be recorded using the KUİK scale and APHAB survey after fitting. They will be called for a check-up at week 1 and month 1, and fitting and scale assessments will be made, and the results will be recorded. Participants' ability to discriminate in noise with the ACT and Turkish Matrix Test, spatial perception with the KUİK scale, and hearing aid satisfaction with the APHAB survey will be assessed at the beginning and month 1. All findings will be compared and statistically analyzed.
