This study established a method of detecting temporomandibular joint sounds based on signal-to-noise ratios. After comparing the temporomandibular joint signals obtained from three different sites over the skin, the articular eminence was found to be the best site for detecting temporomandibular joint sounds; this site provided the highest mean amplitude in(More)
Cervical auscultation is being used more frequently in the clinical assessment of dysphagic patients. The present study was designed to assess symmetry and the reproducibility of swallowing sounds detected simultaneously from bilateral cervical sites. Symmetry of the swallowing sounds acquired using our method was verified because no significant differences(More)
The hearing protectors most often used in noisy workplaces are earplugs. The sound attenuation performance of earplugs depends in part on the user's skill and knowledge. This study sought to clarify whether individual training and self-practice based on a checklist can improve sound attenuation. Measurements were performed as follows: Ten subjects,(More)
In an attempt to gain a better understanding of temporomandibular joint (TMJ) sounds, we recorded joint sounds from 14 non-orthodontically treated dental students, analyzed the acoustic characteristics of the TMJ sounds, and correlated the sound characteristics with axiographic features, morphologic observations of X-ray images and clinical history. The(More)
