Formant 2

Formant 2 (F2) is the second formant frequency. Like Formant 1 it is created by the shape of the tongue; however, its frequency directly related to the height of the Dorsum of the Tongue. That is to say the higher the Dorsum of the Tongue the higher the frequency of...

Formant 1

Formant 1 (F1) is a frequency of increased acoustic resonance caused by the position of the Blade of the Tongue. Formant 1, in conjunction with Formant 2, is responsible for creating vowels. Despite this, formants are excited by acoustic sources and are not the source...

Fundamental Frequency

The Fundamental Frequency or F0, is more commonly referred to as pitch. The difference between the fundamental frequency and a pitch is that a pitch created by a singer or most instruments contains multiple frequencies including the fundamental frequency and...

Echo

An echo refers to the reflection of sound waves off surfaces back to the listener’s ears. It occurs when sound waves encounter a hard, reflective surface and bounce back. The time delay between the original sound and its echo depends on the distance to the reflecting...

Decibel (dB)

Decibel (dB) measures sound intensity or the sound power per unit area on a logarithmic scale. Because of this logarithmic relationship, the overall sound pressure doubles every six decibels. Decibels were named after Alexander Graham Bell. Want to keep...
