Table 2. Difference in hearing thresholds according to the presence of metabolic syndrome.

Characteristics	MetS (-)	MetS (+)	P value
Male
Low-Freq (dB)	14.1 ± 14.3	17.5 ± 14.9	<0.001
Mid-Freq (dB)	20.3 ± 21.0	26.8 ± 21.3	<0.001
High-Freq (dB)	34.9 ± 26.5	43.3 ± 25.4	<0.001
Female
Low-Freq (dB)	12.6 ± 13.9	20.8 ± 17.0	<0.001
Mid-Freq (dB)	13.4 ± 16.4	24.9 ± 19.3	<0.001
High-Freq (dB)	21.8 ± 19.6	37.3 ± 22.1	<0.001

Data are expressed as mean ± standard deviation.

*P values between MetS (-) and MetS (+) were tested using the t-test.

Abbreviations: MetS (-), absence of metabolic syndrome; MetS (+), presence of metabolic syndrome; Low-Freq, low-frequency; Mid-Freq, mid-frequency; High-Freq, high-frequency; dB, decibel.
