I'm a biologist and I was thinking of ways that impulse responses could be used to simulate how an animal sounds over various distances in different types of forests.
Ultimately, if a tool was constructed that would allow scientists to simulate animal sounds over various distances, this would be a pretty useful research tool. Specifically, I'm interested in simulation of the reverberation effects, hence why I'm interested in impulse responses.
Process-based modelling an impulse response is not trivial, however, as an empiracle approximation I was wondering:
- If I record an impulse response at 50m from a source in a forest, if I were to convolve a source signal twice, would that result in a reasonable approximation of what the sound would be at 100m distance?
The idea is that if I can accurately measure impulse responses over short distances in different forest types, these could be used to simulate reverberation over a large distance, including sound passing through multiple forest types. Currently, I can't think of why this would be a bad approach... but I'm a biologist, so I'm hoping others can tell me if this seems like a flawed concept.
