Background: Noise-induced hearing loss (NIHL) is a complex disease caused by environmental and genetic risk factors. This study was to explore the association of noise kurtosis, triphosphopyridine nucleotide oxidase 3 (NOX3) and lifestyles with NIHL.
Methods: This case-control study included 307 patients with NIHL and 307 matched control individuals from Zhejiang province of China. General characteristics, noise exposure data, the exfoliated cells of the oral mucosa, and lifestyle details of individuals were collected. The kompetitive allele specific polymerase chain reaction (KASP) method was used to analyze the genotypes of three single nucleotide polymorphisms (SNPs) of NOX3.
Results: People who exposed to complex noise had a higher risk of NIHL than those exposed to steady noise (adjusted: OR = 1.806, P = 0.002). The GT genotype of additive model and TT + GT genotype of dominant model in NOX3 rs12195525 decreased the risk of NIHL (adjusted: OR = 0.618, P = 0.043; OR = 0.622, P = 0.036). Smoking and exposure to high video volume increased the risk of NIHL (adjusted: OR = 1.486, P = 0.038; OR = 1.611, P = 0.014). Oppositely, regular physical exercise decreased the risk of NIHL (adjusted: OR = 0.598, P = 0.004). A positive interaction was found between complex noise and lifestyles including high video volume exposure and no physical exercise in the additive models (RERI = 1.088, P < 0.001; RERI = 1.054, P = 0.024). A positive interaction was also found between NOX3 rs12195525 GG genotype and lifestyles including smoking and high video volume exposure in the additive models (RERI = 1.042, P = 0.005; RERI = 0.774, P = 0.044).
Conclusions: Noise temporal structure, NOX3 rs12195525 polymorphism, and the three lifestyles of smoking, video volume, and physical exercise were related to the NIHL. There were the interactions between noise temporal structure and the lifestyle of video volume or physical exercise, as well as between NOX3 and the lifestyle of smoking or video volume. These results provide a theoretical basis for the prevention and genetic testing of NIHL.

Article Synopsis
- Noise-induced hearing loss (NIHL) is a significant occupational health issue globally, with a 16% prevalence, and is particularly concerning among Malaysian Armed Forces personnel, especially marine technicians in the Royal Malaysian Navy (RMN), who are at a heightened risk due to prolonged exposure to hazardous noise levels.
- A study conducted with 127 marine technicians from RMN revealed a high prevalence of occupational NIHL at 29.9%, with various factors such as age over 30, household income, military rank, and length of service being significantly associated with the risk.
- The research utilized questionnaires and pure tone audiometric assessments to diagnose NIHL, highlighting the need for awareness and preventive measures within this occupational group.
Occupational Noise Exposure in Foot and Ankle Surgery and the Risk of Noise-Induced Hearing Loss.
Foot Ankle Int

Rothman Orthopaedic Institute, Philadelphia, PA.
Background: Occupational exposure to high levels of noise increases the risk of noise-induced hearing loss (NIHL), resulting in significant long-term quality of life implications. Hearing protection is recommended if occupational noise exposure routinely exceeds 85 decibels (dB). The purpose of this study was to determine if foot and ankle surgeons are exposed to excessive levels of noise, thus putting them at an increased risk for NIHL.

- The study investigates the unknown risk of noise-induced hearing loss (NIHL) for orthopedic surgeons during manual and robotic arthroplasty procedures, aiming to assess if these surgical techniques contribute to this risk.* -
- Researchers collected sound recordings during total knee and hip arthroplasties to measure decibel levels, finding much higher noise levels (106.0 to 108.0 dB) during surgeries compared to baseline controls.* -
- Results indicated that orthopedic surgeons performing robotic-assisted total knee arthroplasties had the highest noise exposure, with doses exceeding safe limits, suggesting a need for protective measures against NIHL.*
