What is the human voice frequency? And why is each persons voice so unique?This is a question that has been asked for centuries. Scientists and researchers have worked tirelessly to figure out what makes each person's voice special.
In this blog post, we will explore what the human voice frequency is and how sound is produced by your vocal cords.
Some people have higher frequency in their voices and some people have lower, more baritone voices. A high-frequency range can be from a few hundred hertz up to several thousand hertz.
The fundamental frequency of a persons complex speech tone lies in the range of 100-120 Hz for lower sounding voices, but variations outside this range can occur. For higher pitched voices the fundamental frequency can be an octave higher around 200 Hz. Children can produce a fundamental voice frequency as high as 300 Hz.
The fundamental frequency of a human voice can also be known as the pitch, or f0.
The below charts show what SPL is produced at each frequency band for various inflections of low, high, and children voices. The SPL is basically how loud the sound is. The higher on the chart the louder the sound.
Low Human Voices
High Human Voices
Keep in mind that the human ear cannot hear sounds above 20 kHz (20 kilohertz). This is why dogs and other animals can hear higher pitched sounds than humans.
How does the human voice produce sound? The vocal cords are located in your throat. When you speak, air passes through your vocal cords and causes them to vibrate. This vibration creates sound waves that travel through the air and into your ears, where they are perceived as sound.
The vocal cords are also known as vocal folds which is the more modern term. Your vocal folds need to vibrate symmetrically and in regularly in order to get crisp and clear sound that is not raspy or harsh.
