A notch in hearing is identified as a frequency drop greater than 15 dB at a specific point compared to adjacent frequencies.
The case report focuses on a 16-year-old with a rare 1 kHz notch in hearing, emphasizing the lack of existing information on its clinical profile.
The findings suggest that potential causes for this notch could be linked to ototoxic medications the patient took for various health issues, like appendix surgery and malaria.
