What Researchers Did
Researchers used EEG-audiometry to measure auditory responses in 5 individuals during simulated dives up to 75 meters (8.5 atmospheres absolute) in a barometric chamber.
What They Found
The study established that the amplitude of all components of auditory evoked responses was reduced while at the maximum depth. During the decompression period, especially in later stages, these amplitudes grew and exceeded their initial levels, particularly for N1P2- and N2P2-components.
What This Means for Canadian Patients
This research suggests that EEG-audiometry could be a valuable method for monitoring the auditory health of divers during and after deep-sea exposures. For Canadian patients involved in diving, this technique might offer a way to assess how pressure changes affect their hearing function.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
This study involved a very small group of only 5 participants and was conducted over 40 years ago, which may limit the generalizability of its findings.
