Abstract Project concerning the study of the relationship of sound frequencies to the behavior of cockroaches with the aim to make. To learn whether the frequency of sound waves that affect the reactions of cockroaches. 22000 Hz and 100 Hz, each adding and changing behaviour observation of roaches. Summarized as follows:
1. from the results of experiments showed that the 15 db sound pressure level of sound at a different frequency will affect the sound wave recognition of cockroaches
2. From the experimental results showed that the 15 db sound pressure level in the frequency range up to 51000 Hz 52500. There are signs to fidget
.3. From the experimental results showed that the 15 db sound pressure level in the frequency range that is higher or lower than the frequency range up to 51000 Hz 52500 affect recognition: the wave of small cockroaches is not responding. His swing back and forth
