Can a person without a tongue hum or whistle?
They would be able to hum because the vibrations created by your vocal chords are amplified through the nasal passages rather than the mouth, so the lack of a tongue would not eliminate humming. Whistling conventionally requires the use of the tongue. Using fingers, it might still be possible to develop a whistling technique, but without a tongue, the whistler would be much less able to control pitch.
How ear defenders effect pitch and amplitude of sound?
I think because as the sound waves loose energy the frequency becomes less frequent so the pitch gets lower
What determines the highness or lowness of a sound?
Its wavelength, or pitch. Sound is only vibrations in the air. If the wavelength of the vibration is low, then it will sound "high". If the vibration has a high wavelength, then it will sound "low".
What is pitch from trees?
I think it's tree sap, I'm not sure...
The pitch of a person's voice varies with the length and thickness of the what?
vocal cords
Which factor would lower the pitch of a string?
The tension of the string. Less tension = lower pitch. This can be achieved by loosening the string or lengthening the string.
How is pitch and loudness changed?
it can be changed by adding tension
How pitch controlled in the human voice?
The pitch of someone's voice is controlled by the tension on the vocal chords
How does a singer regulate pitch?
By adjusting the tension in the vocal chords.
What happens to the pitch of the sound when the tension of the vocal cords increases?
Within the normal range of hearing, the higher the frequency (number of vibrations per second) the higher the perceived pitch. Frequency is a physical characteristic and pitch is a psychological characteristic.
The pitch of sound can be changed by altering the what of material?
In the case of a guitar string, the tension.
What factors create a higher pitch?
tighter tension and shorter air dome
What effect does tension have on pitch?
The tension effects how much the string is capable of vibrating. Different vibrations create different length sound waves so the sound will change at different tensions.
What is the definition of tonometer?
A tonometer is used to determine t the pitch of a tone but it is also a medical device used to measure tension.
How you can change the tension of a vibrating string?
To raise the pitch (frequency), put more tension on one end of the string. To lower the pitch, put less tension on one end of the string.For instance, on a guitar, tighten the string for a higher pitch. Loosen the string for a lower pitch.Additionally, if you have a guitar string already mounted and tensioned. You may place your finger in the middle of the string, and the pitch will go up one octave. Each time you halve a tensioned string, it produces a pitch one octave higher.
How do your vocal cords produce different pitches?
By varying their tension, tighter = higher pitch.
A voice changes from high to low pitch in speaking by?
changing the tension on the vocal cords
