Statistically significant differences were found only in the measurements in air. The range of the maximum peak intensity ranged from 63.0 dB to 100.0 dB.В The lowest peak intensity of decibels was recorded in air with the size 5 Frazier suction and the highest measured was with the size 5 Frazier suction in yogurt. There was a total of 240 repeated observations (10 cadavers, 3 mediums, 2 suction devices 2 investigators). Data was collected with two separate operators and measurers to aid with inter-rater reliability. Under otomicroscopy, the operator would suction the ear canal and the measurer would record the intensity of the sound with a sound decibel meter placed at the lateral and posterior external auditory canal. This was performed with one measurer and one operator. The intensity of the sound generated was measured while suctioning air, water, and yogurt on cadaveric temporal bones with sizeВ 7 and 5 Frazier suctions. We hypothesize that the intensity of the sound would increase with increasing viscosity of the medium and increasing suction diameter. Aural microsuctioning is commonly used in the otolaryngologistвЂ™s office setting for cerumen removal and aural toilet. To determine the loudness of suctioning in the ear canal with different-sized suctions and various mediums.
