Mostly it is high. But you can make low sounds if you pull back your lips a little and make a slower air stream.
What is the name of the insect that lives in a tree and it makes a high pitched sound three seconds at a time when it is hot out in the summer time?
I think it may be a Cicada. Cicadas have large wide eyes apart on their head and possess transparent wings. There about 2500 species around the world. The…y live in temperate to tropical climates and are the most widely recognized of all insects due to their size and vocals.
Pitch is determined by the frequency of the wave; intensity (loudness) is determined by the wave's amplitude. The vibrating source moves in some kind of periodic way, and this… periodic motion will have some given period. The period of a wave is the time it takes for one cycle of that wave, and the number of cycles of a given wave per unit of time is the frequency of that waveform.
Sound is made when air is forced through the vocal chords at the top of the larnyx. The chords sit atop the trachea. When they are constricted, you make a squeeky sound. Whe…n they are relaxed, you make a lower pitch sound. This is done subconscienously.
Low frequency = low pitch = long waves
High pitch = high frequency = short wave Low pitch = low frequency = long wave
Sound waves are more precisely described as pressure waves, caused by an oscillating wave of pressure usually in air. Just like dropping a stone in a pond, the waves move out …from the source, although usually in three dimensions. The sound is perceived by humans as the pressure waves hit the eardrum and are transmitted into the inner ear where small hair-like structures are activated and in turn activate nerves that transmit the information to the brain where it is interpreted as sound.
Yes because the water irritates them
Yes. Likewise, longer wavelengths also produce lower pitched sounds.
