Copulatory vocalizations of several different mammals have different purposes and different frequencies. The calls can be emitted prior the copulation, during or afterwards. Compared to non-human primates, more calls occur prior the copulation. The calls and their properties of mice, elephants, lions and many more are well documented.

It has been shown that mice use 70,000 Hz calls continuously prior to the copulation and some 70,000 Hz mixed with 40,000 Hz calls during the copulation. 1

African elephants for example use low frequency calls of 14-35 Hz while searching for mates. 2
