Summary

This summary is machine-generated.

Hearing aid acclimatization improves speech understanding, even without devices. New hearing aid users showed better sentence recognition thresholds after adaptation, indicating a significant benefit of acclimatization.

Area of Science:

Audiology
Hearing Science
Speech Perception

Background:

Hearing aid adaptation is expected to improve speech understanding through a process called acclimatization.
Understanding acclimatization's impact is crucial for optimizing hearing aid use and patient outcomes.

Purpose of the Study:

To evaluate the effect of hearing aid acclimatization on speech recognition thresholds in quiet (SRTQ) and noise (SRTN).
To assess changes in sentence recognition in new hearing aid users before and after acclimatization, without wearing the devices.

Main Methods:

Forty participants (28-78 years) with mild-to-moderate sensorineural hearing loss were tested.
Speech recognition tests were conducted in three sessions: pre-adaptation, 14 days, and 3 months post-adaptation.
The Portuguese Sentences Lists test was used to obtain SRTQ and SRTN, with noise levels at 65 dB A.

Main Results:

Mean SRTQ values decreased from 54.43 dB A (session 1) to 51.71 dB A (session 2) and 52.22 dB A (session 3).
Mean signal-to-noise ratios improved significantly from 1.67 dB A (session 1) to 0.30 dB A (session 2) and -0.03 dB A (session 3).
Statistically significant differences were found between session 1 and sessions 2/3 for both SRTQ and SRTN.

Conclusions:

A progressive reduction in sentence recognition thresholds and signal-to-noise ratios was observed.
Improved performance, even without hearing aids, suggests a genuine acclimatization effect.
These findings highlight the neuroplastic changes contributing to enhanced speech perception after hearing aid use.
