In general, buzzers carry a narrower frequency range because they are only tasked with outputting an audible tone, whereas speakers offer a wider range to recreate sounds and voice. In this range, sibilant sounds (the unwanted whistle when sometimes pronouncing an ‘s’) and harmonics for certain percussive sounds like cymbals are foundĪ great way to see how a speaker, buzzer, or microphone can reproduce these different frequencies is with the frequency response chart. Harmonics for the violin and piccolo are found hereĪbove 6 kHz is where sounds become more like whines and whistles because they are so high pitched. Here, one can find instruments like the violin and piccoloĪs mentioned, harmonics are at multiples of the fundamental frequency, so if expecting the fundamentals for a trumpet to be in the lower midrange, one can expect the harmonic to be at 2 times, 3 times, and 4 times that fundamental, which would put them in this range The name may be midrange, but it is on the higher end of the fundamental frequencies created by most musical instruments. In the lower midrange are typical brass instruments, and mid woodwinds, like alto saxophone and the middle range of a clarinet This is the low musical range - an upright bass, tuba, bass guitar, at the lower end, will fall into this category Within the 20 Hz to 20 kHz audio frequency range, there are seven subsets of frequencies used to help define the ranges that may be targeted in designing systems for either recording or playback. These harmonics are important for high fidelity speaker systems that want to accurately recreate the original source. For example, that 27 Hz “A” on the piano also produces a 54 Hz harmonic that is much quieter, as well as an 81 Hz harmonic that is even quieter, and so on. Besides these fundamental frequencies, nearly anything that creates sounds also generates harmonic frequencies, which are multiples of higher frequencies, but at a lower amplitude. With a piano, the lowest note, an A, is approximately 27 Hz whereas the highest note, a C, is about 4186 Hz.
The relationship between music and audio frequency is that each time you move up an octave, you double the frequency. The generally established audio frequency range is 20 Hz to 20,000 Hz, though most people can hear less than this entire range, and as they get older, the range tends to contract on both ends. It will also shed some light on when the different audio ranges are needed and when they are not in an end application. This blog will discuss those frequencies and their various subsets as well as how they impact the design of audio enclosures. Quality has many contributing factors but one of them is the ability for a system to recreate the whole range of audio frequencies needed.

When creating an audio system, whether it is for a house, a car, or an embedded or portable device, there is always a balance between cost, size, and quality.
