Noise pollution, operationally defined as 'unwanted sound', has become an environmental contaminant of massive proportions. Noise causes annoyance, frustration, impediment to learning, and general stress. Of all present-day sources of noise, the noise from surface transportation, above all that from road vehicles, is the most diffused and difficult to control. Aircraft, industrial noise, noisy neighbours, and their pets are other familiar sources of noise aggravation. Noise pollution is a harmful environmental impact of sound, which, by its nature, volume, or duration, is likely to have health effects.

This research aims to measure the noise level within the Mallam Aminu Kano International Airport, examine the effects of aircraft noise on employees, assess the awareness level of workers on the impact of aircraft noise, and determine the level of compliance with safety standards.

This study examined the implications and awareness of aircraft noise at the Mallam Aminu Kano International Airport (MAKIA). The noise level within the five selected locations was measured. A noise meter was used to measure the noise at the new fire station, old fire station, international terminal building, domestic terminal building, and main apron. Primary and secondary data were used; fifty questionnaires were randomly distributed to staff from the fire department, aviation security, ground handlers of the Nigerian Aviation Handling Company (NAHCO) and Skyway Aviation Handling Company Plc (SAHCO), airfield staff of the operations department, and airliners. The data obtained from the noise meter were analyzed using the mean noise level, whereas descriptive statistics and simple percentages were used to analyze the data obtained from the questionnaire.

The level of staff awareness of aircraft noise implications due to prolonged exposure and safety regulations was determined. The noise produced within the study area is between 65 and 98 decibels. Seventy-four percent of the responders think that aircraft noise is a nuisance, with more than 50% aware of the implications of noise exposure. In contrast, only 24% have experienced some of the effects of aircraft noise, such as headache, cardiovascular loss, and hearing loss. It was discovered that employers are not providing enough safety kits for their employees, and most staff do not undergo safety training and are not aware of any laws regulating noise. In conclusion, staff need training on noise pollution, its effects, and ways to reduce health implications.
