Background:

Determining auditory thresholds is crucial for understanding hearing sensitivity.
Various stimuli, including tones, noise, and clicks, are used in audiological assessments.
Objective measurement techniques are needed for precise evaluation of auditory function.

Purpose of the Study:

To investigate whether computing signal energy provides consistent absolute and masked thresholds across different auditory stimuli.
To compare thresholds for filtered clicks and broadband signals with varying repetition rates.
To validate the use of brief, narrow-band stimuli for probing auditory sensitivity.

Main Methods:

Absolute and masked thresholds were measured for sinusoids, one-third-octave filtered noise, and one-third-octave filtered clicks.
Thresholds were also assessed for broadband noise and clicks at different repetition rates.
Signal energy was computed for each stimulus type to analyze threshold consistency.

Main Results:

Similar absolute and masked thresholds were achieved when signal energy was computed for all tested stimuli.
Thresholds related to repetition rate and click number aligned with existing data on temporal integration of tones.
The findings demonstrate a direct and objective method for quantifying brief, narrow-band auditory signals.

Conclusions:

Computing signal energy offers a unified approach to determining auditory thresholds for diverse stimuli.
The proposed method is effective for measuring the level of brief, narrow-band signals.
These findings support the application of such signals in objective auditory sensitivity testing.
