Evaluating Listening Behaviours of Nightclub Goers: An International Web-Based Study with Resident Advisor.

Background: Nightclubs expose nearly 40% of young adults in high- and middle-income countries to damaging levels of noise with attendant risk of noise-damage hearing symptoms and sequelae of mood disorders, social isolation and dementia. This study evaluated clubbers hearing symptoms, visiting behaviours and safe listening habits.

Material And Methods: A web-based, population-specific data collection tool was shown to visitors of the dance music website Resident Advisor over a 7-hour period.

Insights on different analysis techniques in the monothermal and bithermal caloric test - which parameter should we use to quantify vestibular function?

Objective: To investigate the use of maximum slow component velocity (MSCV) and time-constant duration (TC) of elicited nystagmus in quantifying the caloric response and to assess the efficacy of these parameters in the monothermal screening test.

Design: Retrospective analysis of caloric results obtained from 150 patients. Bithermal unilateral weakness (UW), directional preponderance (DP), monothermal caloric asymmetry (MCA) based on warm or cool irrigations only, were calculated using both MSCV and TC.
