Hearing loss is not unique to humans and experienced by all animals in the face of wild eclectic differences ear morphology. Here, we exploited high throughput accessible tympanal desert locust, Schistocerca gregaria rigorously quantify changes auditory system due noise exposure age. In this exploratory study, analyzed displacements, morphology Müller's organ measured activity nerve, transduction current, electrophysiological properties individual receptors. This work shows that hearing manifests as a complex disorder differential effects age on several processes cell types within ear. The "middle-aged deafness" pattern found locusts mirrors for exposed early their life suggesting fundamental interaction use an (noise) its aging.
