![]() As an example of a low-frequency noise, turning up the bass on a speaker system will cause the rafters to rumble, and you’ll feel it in your bones. We often feel low frequencies more than we hear them. ![]() The human ear struggles to register waves with low frequency the closer they get to 20 Hz. Low frequencies travel great distances and pass through walls more than others. Low-end noise comes with a longer wavelength, making it some of the most resilient. We perceive these sound waves to have the lowest pitch. Low-frequency sound waves reside at and below 300 Hz. There are three types of sound waves, in general: People may start having difficulty discerning speech once it exceeds about 3,000 Hz-4,000 Hz. Speech usually falls within the 100 and 8,000 Hz range. People with hearing loss usually have trouble hearing sounds in the higher frequency range. Human ears can register sounds from about 20 Hz in frequency up to 20,000 Hz, depending of course, upon the hearer. This measurement of cycles per second is expressed in Hertz (Hz), with a higher Hz representing higher frequency sound. Sound waves are movements of air molecules that our ears translate into sound, and frequency refers to the number of cycles these waves complete in a second. When we talk about sound, we talk in terms of high and low-frequency waves. Get a Free Acoustic Analysis What Is Low-Frequency and High-Frequency When It Comes to Sound? You’re probably aware that different sounds have different frequencies, but what are they? What’s the difference between high and low-frequency sounds? And what about middle-frequency sounds? If you’ve been wondering about the differences between sounds of varying frequencies and how they affect you, read on.
