![]() ![]() Sound pressure level is measured in decibels, a logarithmic unit. The high range of hummingbird vocalizations: 12,000 Hz (Rusch, Pytte, & Ficken, 1996).Typical digital beeps and whistles: 1,500–5,000 Hz (measurements by author).The fundamental frequencies of speech are on the low end fricative consonants like f and s are on the high end. The typical range of human conversation: 80–8,000 Hz (Fant, 2006, p.The low rumbles of thunder: 5–220 Hz (Holmes, 1971).The highest note on an 88-key piano: 4,186 Hz.The lowest note on an 88-key piano: 28 Hz.Some frequencies of well-known sounds are: High sounds such as digital beeps, children singing, and most birdsong have more cycles per second. Low, rumbly sounds have low frequencies, that is, fewer cycles per second. It is measured in cycles per second or Hertz. But frequency and SPL are the most important to understand.įrequency is how high or low the sound is in pitch. There are other qualities that are essential to sound, such as timbre and duration. Sound pressure level (SPL) is a physically measurable quantity that corresponds very roughly to what we subjectively experience as volume. There are two aspects of sound that are most important to understand and identify: frequency (pitch) and sound pressure level. First, we’ll cover a couple of things we need to know about the characteristics of sound. Here is what the experimental literature tells us about dogs’ hearing compared to that of humans. Our capabilities are superior to theirs in a few important ways as well. But their hearing capabilities are not better across the board. Because of this, they have a reputation for superb hearing. They can hear higher-pitched sounds than humans can, and they can hear quieter sounds than we can in some frequency ranges. It’s true that their hearing is better than that of humans in a couple ways. There is a lot of misunderstanding out there about how well dogs hear.
