The effects of noise on people can be classified into three general categories (National Wind Coordinating Committee, 1998):
1) Subjective effects including annoyance, nuisance, dissatisfaction
2) Interference with activities such as speech, sleep, and learning
3) Physiological effects such as anxiety, tinnitus, or hearing loss.
