Why are some deeply more than others?

The voice is one of the main means of humanity and the voices of people are as different as they are many. But why are men’s voices deeper than women’s voices?

Þóra Másdóttir, associate professor of speech pathology, undertook to answer the question in an article that appears on Science Web last week.

She says the difference between people’s voices both biological and individual.

Biological difference

She says that in childhood there is no difference between the sexes of the sexes, but among the changes that the puberty proclaims are voice changes. In the puberty period, however, androgen hormone production increases, for example testosterone production in men.

This has the effect of expanding the larynx and becoming a more proven that describes itself in the so -called Adamse. The voices are prolonged and thickened and the voices are expanded.

The result is that men’s voices are on average 17-22 mm in length, but 11-15 mm in women.

It is during the puberty period that the voice of men often deepens around the eighth, but it deepens only slightly in women.

This quick change in boys’ voice makes them often struggling to manage it. It will be the power of the notorious and often at times a bribe. Gradually, however, they take control of the voice and the basic rate of talk is more stable.

Individual differences and gender analysis

Although the voices of men are, on average, lower in frequency than women’s voices, exceptions to that rule – body height and the shape of barking and hollow above voices also have a significant impact on the frequency and sound of voices.

These differences, along with the voice that are often learned in childhood, causes people’s voices to sound different.

Voice strength different between genders

However, it is not only the voice frequency that is different from women and men, but research suggests that voice strength is also different.

According to the studies, women may find it more difficult to raise the voice to overpower noise, and that could partly explain why women are more likely to damage the voice if they are in an environment where they need a lot to overpower noise.

In trans people, these differences can cause the voice to sound brighter or deeper than the person chooses. In such cases, measures such as hormonal administration are often taken to raise or lower the voice. It is also common for trans individuals to seek help or training in the use of voice in a specialized speech therapist.
