Abstract

This study aims to analyze the noise level of vehicle horn sounds and evaluate their compliance with hearing health threshold limits. The study employed a comparative descriptive method through direct testing on one unit of a Suzuki Ertiga Hybrid vehicle equipped with a factory-standard horn. The testing was conducted in an outdoor area in front of the vehicle inspection workshop using a Sound Level Meter SL-4010. The vehicle was stationary with the electrical system activated and the engine turned off. Measurements were carried out for 5 seconds in each test with distance variations ranging from 2 to 7 meters, front and side vehicle positions, and microphone height variations from 50 to 150 centimeters.The results showed that the highest noise level at the front position of the vehicle was recorded at a distance of 5 meters, reaching 102.9 dBA, while at the side position, the highest value was 100.5 dBA at the same distance. The highest microphone height measurement was obtained at 130 centimeters with a value of 101.7 dBA. Although the test results still complied with the technical standards based on Government Regulation Number 55 of 2012, the recorded noise levels exceeded the safe hearing health threshold of 85 dBA. This study concludes that exposure to vehicle horn noise has the potential to cause hearing impairment; therefore, an evaluation of vehicle noise technical standards that places greater emphasis on health aspects is necessary.
