Why are some voices lower than others?

The deepness of a voice is primarily determined by the length and thickness of the vocal cords. Longer and thicker vocal cords produce lower, James Earl Jones-like pitches. Boys who produced more testosterone during puberty turned into men with thicker and longer vocal cords, and consequently, naturally deeper voices.

Why do some peoples voices carry?

Voices that “carry” contain a pitch of sound that strongly resonates with both the human vocal tract and the human ear, said acoustics expert John Smith, a biophysicist at the University of New South Wales in New Zealand. By comparison, most human speech falls in the gentler 80- to 250-hertz (Hz) range.

Why do children tend to have high pitched voices and why do males typically have lower voices than females do?

As a child has short vocal cords, they produce short air waves and consequently a high pitched voice. As a child grows, the vocal cords become longer. Similarly, the voice of most adult men is deeper than those of women. This is because a man’s larynx is larger than that of a woman.

Why do some voices sound the same?

Although some people might sound quite a bit alike, no two voices are ever exactly alike. As air passes over them, the vocal cords vibrate very quickly to produce sounds. The higher the rate of vibration, called frequency, the higher the pitch will be.

Why are men’s voices deeper in the morning?

A deeper voice in the morning is an inevitable result of a good night’s rest. During sleep, the tissues in our throat collect fluid, which is also what causes our eyes to look puffy when we just wake up. Our lack of vocal cord use during the night also causes mucus to build up during the hours we spend asleep.

Why are some women’s voices deeper?

Women adopted a deeper vocal tone in order to project dominance and authority in a competitive workforce. Fascinatingly, women in countries with more gender equality speak more deeply than women in countries with more traditional values. Women in the Netherlands, for example, speak lower than women in Japan.

Do lower voices carry farther?

The attenuation of sound waves is frequency dependent in most materials. See Wikipedia for the technical details and formulas of acoustic attenuation. As you can see, low frequencies are not absorbed as well. This means low frequencies will travel farther.

What is it called when you can’t control the volume of your voice?

People with dysarthria have difficulty controlling the muscles used to make normal sounds. This disorder can affect many aspects of your speech. You may lose the ability to pronounce sounds correctly or speak at a normal volume.

Why do some females have deeper voices?

Women today speak at a deeper pitch than the generations of women before them, which researchers believe is largely because of changing power dynamics between men and women. Study after study has suggested that low voices and “masculine” voices are an asset to leaders.

What determines your voices volume?

The cartilaginous larynx is situated in the throat, below the tongue and above the lungs. However it is the force and speed of air passing over them which dictates the volume of our voices, and this air originates from the lungs.

Can siblings have the same voice?

Siblings’ voices are of high importance in forensic speaker identification/comparison. Other than being a possible legal strategy, this question suggests itself because siblings often have similar sounding voices (including speech patterns in general).

Why is the sound of each individual’s voice unique?

The sound of each individual’s voice is entirely unique not only because of the actual shape and size of an individual’s vocal cords but also due to the size and shape of the rest of that person’s body, especially the vocal tract, and the manner in which the speech sounds are habitually formed and articulated.

Why do some people have lower voices than others?

In males, the production of testosterone ramps up, and the larynx increases in size. Men that produce higher levels of testosterone during puberty will usually develop lower voices as they grow into adulthood.

Do high-pitched voices make you sound authoritative?

“High-pitched voices, on the other hand, can be unpleasant or cause anxiety.” These sentiments are echoed by Carina Tien, who founded The Voice Room in 2003. She shares that CEOs who are speaking on stage, for instance, tend to tone down their voices in order to be perceived as assertive or authoritative.

What causes sound waves to bunch up?

A sound wave is a pressure wave; regions of high (compressions) and low pressure (rarefactions) are established as the result of the vibrations of the sound source. These compressions and rarefactions result because sound a. is more dense than air and thus has more inertia, causing the bunching up of sound.
