Acceptable Noise Levels Determined by Traditional and Self-Assessed Methods

Area of Science:

• Audiology
• Hearing Science
• Mobile Health Technology

Background:

• Home-based hearing screening apps are increasingly available.
• Traditional acceptable noise level (ANL) measurements require specialized equipment.
• Assessing ANLs is crucial for understanding speech intelligibility in noisy environments.

Purpose of the Study:

• To evaluate the validity of a self-assessed ANL measurement using a mobile application.
• To compare the efficiency of the self-assessed ANL method against traditional ANL measurements.
• To determine if the Unitron uHear app provides a reliable ANL assessment for individuals with normal hearing.

Main Methods:

• A within-subject repeated measures design was employed.
• Sixty-two adults with normal hearing participated in the study.
• Acceptable noise levels (ANLs) were measured using both traditional methods and the Unitron uHear app.

Main Results:

• No significant differences were found between traditional ANL measurements and self-assessed ANL measurements.
• The self-assessed ANL testing using the app was significantly faster than traditional methods.
• The Unitron uHear app demonstrated high validity and efficiency in measuring ANLs.

Conclusions:

• The Unitron uHear app offers a valid and efficient method for self-assessing ANLs in adults with normal hearing.
• Mobile health applications can provide reliable hearing screening alternatives.
• This technology facilitates convenient and accessible hearing health monitoring.
