Similarly, we all know that the loud sound of thunder or a growling animal generally implies danger. And our brain quickly sends signals to our body to either stay and fight or to run away.
On the other hand, a bird singing or the sound of water — like soft rain or a running stream — make us feel relaxed. Andersson says that humans react differently to these live or pre-recorded voice messages depending on the situation and on what type of voice is conveying the message.
In some cultures, women more often have typical service occupations — such as train and flight attendants. This is most likely why audio messages at, for example, train stations and airports use female voices.
However, in other cultures you may only hear male voices in public places. So, that sound coming from outside the hotel room; is it a highway or is it waves crashing on a beach? To summarize: network surveillance systems that combine both sound and vision are a powerful tool for improving safety and security.
Using two senses is, quite simply, more effective than using just one. It is even more critical if you want people to react quickly, or to not miss out on important messages. So it is no surprise that systems that combine cameras and audio are seen as the future for businesses that need high-technology surveillance systems.
Audio, together with visuals gives a fuller picture. Communicating with more than one sense is more effective than communicating with only one. Learn how. Music has the power to trigger feelings in listeners. Three main areas of the brain are responsible for these emotional responses: nucleus accumbens , amygdala , and the cerebellum.
Creators of spooky tunes know exactly what they are doing when they send shivers down the spines of listeners. Recalling a favorite song in our imaginations can bring a private smile. But an earworm is different. Research shows that making music exercises the brain in ways science is only beginning to understand. Eric Friedman Director, Digital Learning. Tiffany A.

Introduction Before American snowboarder Hannah Teter started her routine at the Winter Olympics, she cranked up her inspiration on her MP3 player. How it Works How does your favorite song get from your ears to your brain?
Here are the basics: Sound waves from an instrument or a sound system reach the outer ear. In the middle ear , the sound waves cause the eardrum and tiny bones to vibrate.
The middle ear passes these vibrations to the inner ear. The inner ear includes the snail-shaped cochlea. Inside the fluid-filled cochlea are 20,—30, tiny hair cells.
