Hearing Preservation With Labyrinthine Ablation in Otitis Media Open
Objectives Iatrogenic fenestration of the inner ear in the presence of otitis media is commonly associated with permanent hearing loss. Hearing can generally be preserved when the vestibular labyrinth is ablated in a controlled manner in n…
Intra-Abdominal Sound Pressure Levels during Impulse Noise Exposure in Sheep Open
Ambient sound pressure levels (SPLs) created with intense blasts were compared with SPLs recorded in the abdomen of euthanized sheep. Hydrophones were placed in the abdominal cavity at locations referred to as proximal, medial, and distal …
Effects of noise exposure on latency and strength of contraction of the middle-ear muscles Open
Measurements of latency and strength of contraction of the chinchilla middle-ear muscle (MEM) reflex were obtained before, during, and after an eight-hour exposure to octave-band noise centered at 0.5 kHz at 95 dB SPL. The animals were chr…
