Unlabelled:
Research considers high frequency tonal audiometry as a tool for the early diagnosis of auditory alterations derived from etiological agents.
Aim:
to investigate possible differences in high frequency audiometry of individuals with normal hearing, based on the person who places the earphone.
Patients And Method:
clinical and experimental study with 55 undergraduate students from a country side branch of the São Paulo State University, with normal hearing, underwent two tests each; for the first, the evaluator positioned the earphone on the participant; for the second one, the participant did it by him/herself. An AC40 audiometer calibrated to emit pure tone was used in the frequencies of 10, 12.5, and 16 kHz.
Results:
The kappa(k) coefficient statistical analysis was used to verify the agreement between the two ways of earphone positioning of earphone, bearing a [FORMULA: SEE TEXT]0.70 kappa value as a criterion. Results attained for both ears were below this criterion, with k average of 0.50.
Discussion:
results indicate a risk of compromising the exam reliability when the patient him/herself adjusts phone to his/her own ear.
Conclusion:
when performing audiometric assessment, this variable must be considered in order to attain reliable results.

Perceiving Loudness, Pitch, and Location
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by identifying...

Interference: Path Lengths
Two special sources may be considered when they are in phase. This can be easily achieved by feeding the two sources from the same source. An example would be synchronizing the two speakers by feeding them with the same source, such as the sound waves produced by a tuning fork. This setup ensures that the two sources have the same frequency and are...
