Auditory Processing Testing: In the Booth versus Outside the Booth.

Area of Science:

• Audiology
• Auditory Processing
• Speech-Language Pathology

Background:

• A common belief among audiologists is that auditory processing testing necessitates a soundproof booth, posing challenges in environments like elementary schools.
• Existing research on pure-tone thresholds does not consistently support the need for soundproof booths, especially for auditory processing tests conducted above threshold levels.

Purpose of the Study:

• To evaluate the feasibility of administering auditory processing tests in a quiet room as an alternative to a soundproof booth.
• To demonstrate that audiologists can effectively conduct auditory processing testing for children in various settings, including quiet school rooms.

Main Methods:

• A battery of auditory processing tests was administered to 20 participants with normal hearing (10 with and 10 without auditory processing concerns).
• Testing was conducted both inside a soundproof booth and outside in a quiet room using identical equipment and a standardized test level of 50 dB HL.
• The order of testing (booth vs. room) was counterbalanced across participants.

Main Results:

• No statistically significant differences were observed in auditory processing test results based on the testing environment (soundproof booth vs. quiet room).
• The order of testing did not influence the outcomes, indicating consistent performance regardless of whether participants were tested first in the booth or the room.

Conclusions:

• Auditory processing tests can be reliably administered in a quiet test environment, yielding comparable results to those obtained in a soundproof booth.
• Audiologists are not strictly required to use soundproof booths for auditory processing testing, provided background noise is adequately controlled.
• This study supports the use of quiet rooms for auditory processing assessments, enhancing accessibility in diverse clinical and educational settings.
