Abstract
•Threshold shifts from a free field exposure to 11 kHz of 124 dB SPL recover in one week.•ABR wave I amplitude is chronically reduced, but wave IV recovers in a week.•Spontaneous rates of inferior colliculus neurons are unaffected.•Stimulus-evoked inhibition was reduced but recovered within two to four weeks.•The increased central gain suggests a possible mechanism for hyperacusis.
