Speech Perception, Spatial Perception and Satisfaction Outcomes of Fitting Based on Hearing In Noise Ability
2026년 8월 8일 업데이트: Melek Başak ÖZKAN, Istanbul Aydın University
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.

활성 비교기: Experimental Group
The ACT method will be applied to the study group in fitting, and the results will be recorded by applying the KUİK scale and APHAB survey after fitting.
They will be called for control in the 1st week and 1st month, and fitting and scale evaluations will be made and the results will be recorded.
Participants' discrimination in noise with ACT and Turkish Matrix Test, evaluation of spatial perception with the KUİK scale, and hearing aid satisfaction with the APHAB survey will be evaluated in the initial and 1st month time periods.

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.

활성 비교기: Control Group
The control group will be fitted with traditional fittings, and the results will be recorded using the KUİK scale and APHAB survey after fitting.
Fitting and scale assessments will be made at week 1 and month 1, and the results will be recorded.
Participants' ability to discriminate in noise with the ACT and Turkish Matrix Test, spatial perception assessment with the KUİK scale, and hearing aid satisfaction with the APHAB survey will be assessed at the beginning and month 1.

Eco-HINT
기간: 1 week and 1 month after hearing aid fitting
|
Speech-in-noise performance was assessed using the ecologically valid Hearing in Noise Test (eco-HINT).
Speech reception thresholds were measured under aided and unaided listening conditions.
Lower scores indicate better speech-in-noise performance.

Speech, Spatial Perception and Hearing Quality Scale
기간: 1 week and 1 month after hearing aid fitting
|
The individual who is applied the scale evaluates himself/herself and answers each question between 0 and 10 points.
All scores are added up and divided by 49 to obtain the "General KUİK score".
The scores under the heading of Speech Perception are added up and divided by 14 to obtain the KA score, the scores under the heading of Spatial Perception are added up and divided by 17 to obtain the UA score, and the scores under the heading of Hearing Quality are added up and divided by 18 to obtain the İK score.

APHAB survey
기간: 1 week and 1 month after hearing aid fitting
|
APHAB is a survey that allows us to numerically measure the benefits and satisfaction of individuals with hearing loss from their hearing aids in daily hearing situations.
Survey questions are answered according to two different listening situations: "without my hearing aid" and "with my hearing aid".

Audible Contrast Threshold (ACT)
기간: Time Frame: 1 week and 1 month after hearing aid fitting
|
The ACT is a suprathreshold, non-language-specific test that measures an individual's ability to hear in real-world noisy environments to determine the level of assistance needed in noise.
ACT values are determined by level of intensity.
A normal ACT value is between -4 and +4 dB nCL. 4 to 7 dB nCL indicates mild loss, 7 to 10 dB nCL indicates moderate loss, and 10 to 16 dB nCL indicates profound loss.

IPD 계획 설명
To ensure the privacy and confidentiality of participants, individual participant data (IPD) will not be shared.
Since the study involves hearing aid users, it is extremely important to protect the integrity of their personal data.
Furthermore, the guidelines of the ethics committee and institutional policies require strict data protection to prevent possible misuse.
Therefore, IPD will remain confidential and will not be made public.
