HELICOPTER NOISE IN RURAL COMMUNITIES: ASSESSMENT OF EXISTING KNOWLEDGE

Existing knowledge on helicopter noise focused on the effects of distance and altitude on ground-level noise, the annoyance caused by helicopter noise expressed by people, and the consequences of findings for helicopter operations in rural areas. A nonlinear association between ground-level noise, altitude, and slant distance was identified. A combination of altitude, standoff distance, and cruise speed for each helicopter type at which ground level noise is minimum appears to exist. Also there is a considerable difference between desired and actual noise levels for rural areas even if penalties are not assessed on the measured helicopter noise. A gap in the connection between actual helicopter noise measurements and community annoyance was also revealed. Specific guidelines or regulations that define paths (separation), the frequency of helicopter flights per path, and the minimum standoff distance and altitude may be necessary for semirural and recreational areas.
