Hyperacusis assessment within the selected studies. VAS = Visual Analogue Scale; MASH = Multiple-Activity Scale for Hyperacusis; THI = Tinnitus Handicap Inventory Test; TSCH = Tinnitus sample case history; PTA = Pure tone audiometry; OAE = Otoacoustic emission; SAT = Speech audiometry test; IT = Immittance test.

Hyperacusis Grading	VAS from 1 to 10: Hyperacusis present in 57 (18.4%) patients at an intensity ranging from 1 to 10 and a median of 5.	TSCH 20 patients (54%) reported hyperacusis (grading not provided).	5 groups based on annoyance score (a)no hyperacusis; (b)mild; (c)moderate; (d)substantial hyperacusis; (e)severe hyperacusis.	(a)4 moderate; (b)1 severe; (c)1 mild
Results	The presence of hyperacusis more frequent in the male gender; 31 (22.4%) men and 26 (15.3%) women.There was no statistically significant difference between genders (p = 0.12).	No statistically significant differences between genders according to THI scores TSCH (a)20 patients reported sleep disorders (54%); (b)20 patients reported hyperacusis (54%); (c)11 patients (30%) sleep disorders + hyperacusis. THI (d)slight (1 pt,16%), (e)mild (6 pt, 32%), (f)moderate (7 pt, 30%), (g)severe (5 pt, 19%), (h)catastrophic (1 pt, 3%).	Comparable prevalence in both genders: males (80.5%; 116/144); females (77.1%; 81/105). Improvement over time is better for Hyperacusis (19/30; 63.3%), than for tinnitus (15/32); 46.8%).	Women are affected more often than men. Tinnitus preceded hyperacusis as a complaint in 78% of the subjects. No direct correlation between the severity of tinnitus and of hyperacusis
