Summary

This summary is machine-generated.

Low-frequency tones (LFT) and infrasound (IS) can activate the auditory cortex in healthy individuals. This brain activation is dependent on sound pressure levels, with potential clinical implications for LFT-related disorders.

Background:

Low-frequency tones (LFT) and infrasound (IS) are suspected to pose health risks.
Understanding their impact on the auditory system is crucial.

Purpose of the Study:

To investigate LFT/IS-induced activation of the auditory cortex using functional magnetic resonance imaging (fMRI).
To assess the relationship between sound pressure levels and auditory cortex response.

Main Methods:

fMRI scans were performed on 17 healthy volunteers.
Stimuli included 12, 36, 48, and 500 Hz tone bursts delivered via a specialized ear canal system.
In-situ measurements of sound pressure levels and spectral analysis were conducted using optical and fiber-optic equipment.

Main Results:

Sound pressure level-dependent activation was observed in the superior temporal gyrus (Brodmann areas 41, 42, and 22) for 12, 48, and 500 Hz stimuli.
Brain activation thresholds for LFT/IS ranged from 90 to 110 dB SPL in participants with normal hearing.
Harmonics present with LFTs, particularly 36 Hz, were found to interfere with 12 Hz IS exposure and scanner noise.

Conclusions:

The study provides evidence that LFT/IS exposure can induce auditory cortex activation, contingent upon applied sound pressure levels.
Further research involving patients with suspected LFT-dependent disorders is needed to explore clinical implications.
