Sound in water and sound in air are both waves that move similarly and can be characterized the same way. Sound waves can travel through any substance, including gases (such as air), liquids (such as water), and solids (such as the seafloor). In fact, sound cannot exist if it doesn’t have something to travel through! For example, sound cannot travel through outer space because it is a vacuum that contains nothing to carry sound. Something else that’s interesting in the differences between sounds in water vs. through the air is how vowels and consonants sound. The next time you’re in a pool with friends, duck your head under water and listen to their conversation. If they talk loud enough, yo
As we age, our senses (hearing, vision, taste, smell, touch) change, becoming less sharp, and this can make it harder for us to notice certain details. Sensory changes can affect our lifestyle, making it more difficult communicating, enjoying activities, and staying involved with people. In some cases, sensory changes can lead to isolation. Our senses receive information from our surroundings. This information can be in the form of sound, light, smells, tastes, and touch. Sensory information is then converted into nerve signals which are carried to the brain. There, the signals are turned into meaningful sensations. A certain amount of stimulation is required before you become aware of a se
Ever flown across the friendly skies and had that feeling your ears were filled up and ready to pop any minute? Ear popping is caused by pressure differences between the inside and outside of the eardrum. Air pressure in the middle ear usually is the same as air pressure outside the body. Most people are familiar and can cope with the pressure changes (relieved by ear popping) that occur when you fly, travel to high altitudes, or dive underwater. In most cases, swallowing or yawning helps relieve the pressure by opening the eustachian tube, which then connects the middle ear to the back of the nose and upper throat. Opening the tube allows air to flow into or out of the middle ear and equali
