Not all sounds have a pitch even though all have frequency content

Evidence

In many cases, pitch can be considered a perceptual correlate of frequency: Increases in frequency are often associated with increases in the perceived pitch. Yet, the terms frequency and pitch are not interchangeable — pitch is a perceptual attribute, whereas frequency is an acoustic property. It is misleading to substitute the word pitch when one means frequency and vice versa. Notably, as we will see in this chapter, factors other than frequency influence the pitch of sounds. Even more importantly, not all sounds have a pitch, even though all sounds have frequency content. This reason alone is compelling enough to avoid the common mistake of interchanging these two, rather different, terms. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 1168
