If the sound acceleration time is slower than 10 ms, the brain pathway changes and the signal is processed by the avian auditory cortex; thus not initiating ASR. The results from our experiments show that when the signal (112 dB @ 1m./3.3 feet, increasing in less than 10 ms) causes the reflex reaction, it makes the birds sensitize to the ASR signal instead of habituate to repeated use of the same initiating signal.
