Best Ear Devices

This group was testing sound waves and a humans ability to distinguish sounds accurately in devices presses into the ear (earbuds) vs devices placed on top of the ear. The results showed that the earbuds more accurately enabled the listener to hear voices as the sound waves were more concentrated.

Sensory Adaptation with Smell

This group discovered that odors from molecules can overload our senses over time and we lose our ability to smell that particular odor. When a new smell is introduced, it resets our senses and then we can more accurately recognize the original scent. This group used orange peels and coffee. The coffee was used to reset the stimulus so students could again detect the intensity of the orange peels.
