TABLE 1.

Prevalance of and number of individuals aged 60+ with a hybrid^a CI or conventional^b CI audiometric profile

	Hybrid CI Audiometric Profile (Better Ear)			Hybrid CI Audiometric Profile (Worse Ear)			Conventional CI Audiometric Profile

^aHybrid audiometric profile defined as a threshold at 0.5 kHz, ≤60 dB HL, and a high-frequency (2, 3, and 4 kHz) PTA threshold ≥75 dB HL.

^bConventional CI audiometric profile defined as a better-ear 4-frequency (0.5, 1, 2, and 4 kHz) PTA >60 dB.

^cTotal count is the sum of counts by age decade. Total count includes overlap in individuals meeting hybrid and conventional CI candidacy. In 2020, 1.05 million adults aged 60+ meet better-ear audiometric criteria for both devices, increasing to 2.04 million in 2060. The number of unique individuals meeting better ear audiometric criteria from implantable hearing devices is 2.38 million in 2020 and 4.64 million in 2060.

CI indicates cochlear implant; 95% CI, 95% confidence interval.
