A stratified sample using would be the best choice as it allows for the population to be divided into subgroups or strata based on factors that may affect noise levels, such as the type of aircraft or time of day. This method ensures representation from each stratum and can provide more precise estimates of the noise levels compared to a simple random sample or judgment sample. Additionally, a radio survey of pilots would not necessarily provide accurate measurements of ground-level noise.
