Ray-tracing of drone noise
The in-house ENVironmental Acoustic Ray-tracing Code (EnvARC) at the AANTC generates acoustic maps using generalized acoustic sources, generic terrain and building models with user-defined impedances, and resolves the effects of atmospheric sound absorption and refraction. The inputs consist of the noise source and environmental scenario models as well as the observer positions. The output is the noise exposure map for noise evaluation and abatement.
