During a non-manual hearing test, how long should each tone be presented?

In a non-manual hearing test, each tone is typically presented for a duration of 1 to 2 seconds. This duration is deemed optimal because it allows for sufficient time for the participant to perceive and respond to the tone without causing listener fatigue or confusion. Shorter presentation times help maintain the participant's attention and minimize the likelihood of errors in response. Prolonged presentation times can lead to diminishing returns, as they may lead to decreased responsiveness or attention from the subject being tested. Therefore, maintaining a range of 1 to 2 seconds ensures effective testing while accommodating human response capabilities.
