In order to hear a sound, three things are needed: a source of sound producing vibrations, a medium such as air or water for the vibrations to travel through, and the ear to receive and interpret the vibrations as sound.
To make sound, three things are needed: a source of vibration, a medium through which the sound waves can travel, and a receiver to detect and interpret the sound waves.
The three things that affect the frequency of a sound wave are the source of the sound (vibration frequency), the medium through which the sound wave is traveling (speed of sound in the medium), and the relative motion between the source of the sound and the observer (Doppler effect).
Three things that have the same beginning sound as net would be not, never and normal.
The three things Thomas Edison invented are... 1. Electric lighting 2. Sound recording 3. Motion pictures
There are three components in the production of sound. The first thing you need is a physical object that is vibrating, because vibrations create sound. The next thing you need is a medium to carry out the vibrations. The last necessary piece in the production of sound is an ear to hear the sound and turn it into something meaningful. These three things are as simple as a person playing an instrument to a crowd.
Three things that transfer energy by sound are speakers (electronic devices that convert electrical signals into sound waves), musical instruments (objects that produce sound when vibrations are created), and vocal cords (bodily structures that generate sound during speech or singing).
The three media of sound are solid liquid and gas.
The "s" in "things" is a "z" sound.
The three main things that transfer energy through sound are mechanical waves, vibrations, and particles. Sound energy is carried through a medium by creating vibrations in the particles of that medium, which in turn propagate as mechanical waves that transfer energy from one point to another.
Sound! It normally mode of propagation IS in three dimensions.
