| WHAT IS SOUND | vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear. |
| what is compression | the action of compressing or being compressed |
| what is a sound wave | a wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air. |
| what does rarefactions mean | reduction in the density of something, especially air or a gas. |
| this is a common diagram of soundwaves in our everyday one | |
| what is a longitude wave | are waves in which the displacement of the medium is in the same direction as, or the opposite direction to, the direction of travel of the wave. |
| what is a vibrating speaker | |
| how fast is the speed of sound | 1.079e+9 km/h THAT'S LIKE.. |
| types of waves | Longitudinal wave *s - Movement of the particles are parallel to the motion of the energy. Sound waves moving through the air is an example of this type of wave. Transverse wave *s - movement of the particles are at right angles (perpendicular) to the motion of the energy. |
| where does sound go? | they can usually goo up into the hemisphere |
| Did you know that a fighter jet travels at about the speed of sound | WOW!!!!!!! |
| these are different materials will give a room different reverberation times | in an unfurnished room in a furnished room, sound is absorbed by soft like heavy curtains, cushions and floor covering |
| what is an infrared sound? | Infrasound, sometimes referred to as low-frequency sound, is sound that is lower in frequency than 20 Hz |
| frequency and pitch of sound | A high pitch sound corresponds to a high frequency sound wave and a low pitch sound corresponds to a low frequency sound wave. Amazingly, many people, especially those who have been musically trained, are capable of detecting a difference in frequency between two separate sounds that is as little as 2 Hz. |
| musical instruments | All musical instruments produce sound by vibration, they all produce ways and produce sounds of different characteristic qualities |
| How do we then hear all these vibrations? | well, your ears collect soundwaves, amplify there vibrations and convert them into electrical impulses. |
| these are some musical instruments notes that were viewed on the (CRO) | guitars make oboe noises and pionos make laud obstacular noises |
| what is a cro? | a cro converts sound waves into electrical signals that can be viewed on a screen |
| this is a typical sound absorption values |
