The 4K notch is a common audiological phenomenon in which there is a dip in a person's hearing sensitivity centered on or near 4000 Hz. This dip is caused by damage to the hair cells in the cochlea, and thus presents as sensorineural hearing loss.

Despite this variability, a notch metric showed excellent agreement with expert notch consensus in each sample (94.7 and 96.6%; kappa = 0.88 and 0.92). Conclusions: Audiogram notch metrics can agree with expert clinical consensus and assist in the surveillance of noise-exposed workers.
Notched Audiograms and Noise Exposure History in …
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2811687/
This may be reflected in the audiogram as hearing thresholds that reach a maximum between 3–6 kHz and then return toward the normal level at higher frequencies, forming a noise notch. A notched audiogram, together with a positive history of noise exposure, has been gradually accepted as a clinical sign of NIHL (McBride & Williams, 2001).
