White noise
White noise is created vocally through the initial consonant "sh" and variations such as s, z, wh, p, t, h, ct, d, ch, th, k, and sw. Ring modulation is imitated through rapidly changing the vowel content, percussive envelopes through "lip pops," "tongue clicks," "snap fingers," and "flutter lips", and filtering through muting such as by covering the mouth with one's hand, sounding the consonant "M" through tightly closed lips, or singing through clenched teeth.
