Annoyance reactions caused by intermittent noise

Annoyance Caused by Aircraft En Route Noise

A laboratory experiment was conducted to quantify the annoyance response of people on the ground to en route noise generated by aircraft at cruise conditions. The en route noises were ground-level recordings of eight advanced turboprop aircraft flyovers and six conventional turbofan flyovers. The eight advanced turboprop en route noises represented the NASA Propfan Test Assessment aircraft oper...

Annoyance caused by amplitude modulation of wind turbine noise

A listening test has been performed to investigate the relationship between human annoyance and the amplitude modulation of wind turbine noise. To obtain sound samples for the listening test, sound from a 1.5 MW wind turbine in Korea was recorded. The strength of the amplitude modulation of the sound samples was defined in terms of the modulation depth spectrum, which was approximated by assumi...

Experimental Investigation of Noise Annoyance Caused by High-speed Trains

The observed difference in perceived annoyance caused by train and highway noise at the same averaged noise level, has led to the introduction of the ‘railway bonus’. This bonus has found its way to the noise legislation in many countries, leading to more relaxed restrictions on time averaged noise levels, LAeq. With the introduction of high-speed trains and train-like transportation systems ba...

Influence of visual factors on noise annoyance evaluation caused by road traffic noise in indoor environment

Through laboratory experiments the variation of noise annoyance caused by road traffic noise with LAeq.20sec of 35, 45, 55 and 65dB under different visual conditions in study and living rooms was explored. The experimental result shows that in the indoor environment the influence of brightness perception on noise annoyance caused by road traffic noise was more obvious, and the effect of color p...
