How do you squeak?

You squeak by forcing air through a narrow opening or creating friction between surfaces that vibrates at high frequency. With your voice, to squeak, tighten your throat, raise your larynx, and push air out while saying eek in a very high-pitched falsetto voice like a mouse, keeping it short and sharp. You can also inhale slightly while making eek sound to get squeakier tone. With your nose, try to laugh while holding mouth closed, air escapes through nose and squeaks. With your hands, wet your finger and rub it on a balloon or clean glass, the stick-slip friction creates loud squeak. With shoes, twist rubber soles on polished floor quickly. With objects, squeeze a squeaky toy that has a built-in reed. With a balloon, inflate and stretch neck while letting air out slowly. If you want to squeak like a door, say skreeeek with long e sound. Practice by starting with week and making it higher and shorter. The technique involves high pitch, short burst, and tension. Most people can squeak by imitating mouse saying squeak squeak in high voice. It may take practice to control pitch and not strain voice, so keep squeaks brief.
