Hypersensitivity of Vestibular System to Sound and Pseudoconductive Hearing Loss in Deaf Patients

Table 2

Air- and bone-conducted hearing thresholds (250 Hz and 500 Hz) in unaffected ears.

Case number	ACHT (dBHL)		BCHT (dBHL)
	250 Hz	500 Hz	250 Hz	500 Hz
1	95	95	40	65
2	90	95	35	55
3	100	105	45	55
4	100	110	40	65
5	95	110	45	65
6	90	110	35	50
7	100	105	45	60
8	100	115	45	65
9	95	95	40	50
10	95	95	45	60
11	100	100	45	50
12	95	105	40	60
13	100	110	40	55
14	95	115	35	55
15	90	100	35	40
16	100	110	45	60
17	100	120	45	65
18	95	120	45	65
19	100	100	40	60
20	95	105	35	55

The mean of air-conducted hearing thresholds (ACHT): 250 Hz = 96.5 dBHL, 500 Hz = 106 dBHL.
The mean of bone-conducted hearing thresholds (BCHT): 250 Hz = 41 dBHL, 500 Hz = 57.75 dBHL.
