The four types of noise are physical, physiological, psychological, and semantic.

Here are 17 of the most recognized:

• NBC’s musical notes G, E, C played on chimes.
• MGM’s lion’s roar.
• The song “Sweet Georgia Brown” for The Harlem Globetrotters.
• Tetris’ “electronic Russian folkstyle tune,” owned by Elorg Company.
• Intel’s 5 note ding.
• “

Sound is a vibration, or wave, that travels through matter (solid, liquid, or gas) and can be heard. How does sound move or propagate? The vibration is started by some mechanical movement, such as someone plucking a guitar string or knocking on a door.

Sound waves can also be thought of as pressure waves. This is because the compressions and rarefactions that move through sound waves have different pressures. The compressions are areas of high pressure while the rarefactions are areas of low pressure.

Make sounds with several different instruments. For example, ring a bell or strike a triangle, xylophone, or drum. Ask students if they can see these instruments vibrating. Ask them how the sounds get from the instruments to their ears.

Sound is created when something vibrates and sends waves of energy (vibration) into our ears. The vibrations travel through the air or another medium (solid, liquid or gas) to the ear. The stronger the vibrations, the louder the sound. Sounds are fainter the further you get from the sound source.

Sound is a vibration, or wave, that travels through the air. Sound waves are invisible to our eyes; unless we find a way to make the sound waves move something that we can see. In this activity, your child will use different noise-making objects to cause sound waves and make sand visibly move.

The cumulative signals from these cells give our brain enough information to create the incredible sense of vision. Thus, because sound waves have nothing to do with the electromagnetic radiation which our eyes are equipped to detect, we will never be able to “see” sound directly.

Synesthesia is when you hear music, but you see shapes. Or you hear a word or a name and instantly see a color. Synesthesia is a fancy name for when you experience one of your senses through another. For example, you might hear the name “Alex” and see green.

ABSTRACT. Synaesthesia, a mixing of the senses, is more common in individuals with autism. Here, we review the evidence for the association between synaesthesia and autism with regard to their genetic background, brain connectivity, perception, cognitive mechanisms and their contribution to exceptional talents.

The synesthetes showed increased intelligence as compared with matched non-synesthetes. The personality and cognitive characteristics were found related to having synesthesia (in general) rather then to particular synesthesia subtypes.

No, synesthesia is not a disease. In fact, several researchers have shown that synesthetes can perform better on certain tests of memory and intelligence. Synesthetes as a group are not mentally ill. They test negative on scales that check for schizophrenia, psychosis, delusions, and other disorders.

Ordinal-linguistic personification (OLP, or personification for short) is a form of synesthesia in which ordered sequences, such as ordinal numbers, days, months and letters are associated with personalities and/or genders (Simner & Hubbard 2006).

Synesthesia is an anomalous blending of the senses in which the stimulation of one modality simultaneously produces sensation in a different modality. Synesthetes hear colors, feel sounds and taste shapes.

People who experience synesthesia are usually born with it or develop it very early in childhood. It’s possible for it to develop later. Research indicates that synesthesia can be genetically inherited . If you have synesthesia, you may also feel like you can taste the color of the wall while you look at it.

While synesthetes range in mathematical ability just as non-synesthetes do, individuals with certain types of synesthesia may have to view the mathematical processes a little differently. For an individual with OLP synesthesia, for instance, math can be at times uncomfortable.
