Bibliometric analysis and review of auditory and non-auditory health impact due to road traffic noise exposure

Abstract

This paper presents a bibliometric and critical review of auditory and non-auditory health impacts due to road traffic noise exposure. The paper discusses the general trends of studies conducted in the research domain using the bibliometric network approach. These networks are based on citation, bibliographic coupling, and co-authorship relationships. Further, a critical review is conducted to summarise the auditory and non-auditory impacts due to traffic noise exposure. Auditory health impact issues such as noise-induced hearing loss (NIHL) and tinnitus are presented. Non-auditory impacts are categorised as physiology and performance-related impacts. Physiology related health impact includes a review of cardiovascular and sleep disturbance issues due to noise. Performance-related health impact includes annoyance and cognitive impairment issues. This paper discusses the severity level, different exposure-response relationships, techniques, and empirical models developed to assess the magnitude of these health impacts. Subjective and laboratory assessment techniques used to analyse the health impact through various modeling and statistical approaches are considered. Additionally, a scenario analysis of health impact due to heterogeneous transportation is performed. An assessment is done to find the applicability of health risk prediction models in heterogeneous traffic conditions.
