WebStudents measure the wavelength of sounds and learn basic vocabulary associated with waves. As a class, they brainstorm the difference between two tuning forks and the sounds they produce. Then they come up with a way to measure that difference. Using a pipe in a graduated cylinder filled with water, students measure the wavelength of various tuning … WebSound pressure or acoustic pressure is the local pressure deviation from the ambient atmospheric pressure, caused by a sound wave. In air, sound pressure can be measured using a microphone, and in water with a hydrophone. Table of contents Sound pressure and sound pressure level Frequency weighting curves

It is simply the size of a wave, measured from one peak to the next. If one imagines a sound wave as something like a water wave, then the wavelength is simply the distance from the crest of one wave to the next nearest crest. Thus, if the distance between two peaks is 1 m, then the wavelength is …
