What causes sound to have different pitches?
Sounds are determined by how an object vibrates. Sound travels more slowly than light. Sound waves travel at the same speed, but vibrate in different ways. Some vibrate quickly and have a high frequency or pitch, while others vibrate slowly and give a lower pitch.
What causes high frequency noise?
The most common cause of tinnitus is damage and loss of the tiny sensory hair cells in the cochlea of the inner ear. This tends to happen as people age, and it can also result from prolonged exposure to excessively loud noise. Hearing loss may coincide with tinnitus.
What affects sound intensity?
Intensity results from two factors: the amplitude of the sound waves and how far they have traveled from the source of the sound. It depends on the amount of energy that started the waves. Greater amplitude waves have more energy and greater intensity, so they sound louder.
How do you calculate loudness?
It is defined as dB = 10 * log10(P 1/P 2), where P1 and P2 are the relative powers of the sound. phon: A unit of apparent loudness, equal in number to the intensity in decibels of a 1,000-hertz tone judged to be as loud as the sound being measured.
Which nail produces the highest sound?
When you hit a nail into wood, the nail starts longest, making the biggest vibrations, causing the sound to be lower. As the nail gets driven in, the vibrations get smaller and smaller, making the pitch higher.
Can high frequency sounds make you sick?
High frequency sound causes two types of health effects: on the one hand objective health effects such as hearing loss (in case of protracted exposure) and on the other hand subjective effects which may already occur after a few minutes: headache, tinnitus, fatigue, dizziness and nausea.

How to calculate the intensity of a sound source?
1. Point A and B located at 4 meters and 9 meters from a source of the sound. If IA and IB are intensity at point A and point B, then IA : IB =… 2. The intensity of a source of sound is 10−9 Wm−2.
