What is Sibilance?

Sibilance refers to the sharp, hissing sound that occurs when certain consonants are spoken or sung, particularly “S,” “Sh,” “Z,” and “Ch” sounds. These sounds produce strong high-frequency energy that can stand out in a recording.

In vocal recordings, excessive sibilance can make a voice sound harsh or overly bright. Microphones, especially sensitive condenser microphones, can sometimes emphasize these high-frequency sounds, making the effect more noticeable.

Audio engineers often control sibilance using techniques such as microphone positioning, pop filters, and de-esser processors. A de-esser reduces the volume of harsh high-frequency sounds only when they occur, helping to create a smoother and more balanced vocal recording.
