TMS is associated with a click which can have a 120 dB peak sound level at maximum stimulator output. Studies in adults and children have shown no long-lasting or permanent hearing loss after TMS, but there is no information regarding transient decrease in hearing thresholds immediately after TMS as can occur after listening to music through headphones using personal cassette recorders. As part of the main study, we will be conducting a safety study to determine the risk for temporary hearing loss after TMS in children.
