Efforts to the scale of effective perceived noise level (EPNL) to account for the subjective effects of impulsive helicopter noise are reported. Psychoacoustical studies of the annoyance of recorded and simulated helicopter noises are described and an objective descriptor of impulsiveness is developed. This descriptor forms the basis of a draft standard for an impulse correction to EPNL.
