Investigation of the Impacts of Aircraft Acoustics
摘要
The work deals with the analysis of effect of aircraft acoustics on human. In this study, measurement and analysis of cargo and fighter aircraft noise at close vicinity of a military airbase was done with sound measurement device. The results shows that noise level during takeoff and landing is greater than 85 dB and people living near to close vicinity of military airbase. To support this work, population-based questionnaire technique and a field study was designed. In population-based questionnaire study, 50 nearby residents were given the questionnaire and 45 residents returned back the filed questionnaire. This research included responses from long-term inhabitants of a military airfield. In addition, human individuals were subjected to three-day controlled research with 90-min sessions each day. Thirty volunteers took part in the field study and reported their opinions on irritation, speech interruption, and perception. The investigation reveals a substantial relationship between the total irritation response and the acceptance of aeroplane noise. The amount of responses demonstrates that people are severely or extremely irritated by aeroplane noise.
