Vibration

1. The occlusion effect amplifies bone conducted sounds because as the bone oscillator vibrates the mastoid bone and thus the skull. The skull creates vibrations in the cochlea, displacing the endolymph and creating sound waves back through the inner ear to the middle ear and then to the outer ear canal. In an unoccluded ear, these vibrations would escape out the exterior auditory canal. However, when the ear canal is occluded, the sound waves have no where to go and therefore circulate in the…

plotting out the Forward Edge of the Battlefield (FEBA), and locating and identifying logistical support areas and major supply routes (MSR). There were significant issues with the existing airframes and camera systems as they were susceptible to vibration and covered very limited areas directly below the aircraft at NADIR or offset to slight angles. Other issues which limited the full utility of aerial reconnaissance was the limited range of…

Inside a speaker a permanent magnet and an electromagnet form a magnetic field. Electricity is used to constantly reverse the poles of the electromagnet. When the poles switch, it causes a disruption in the magnetic field, which makes vibrations. These vibrations are then made into sound. Another device that utilizes is the MRI (magnetic resonance imaging) machine. MRI devices use powerful doughnut-shaped electromagnets to create a magnetic field around a patient’s body. The charges in the atoms…

Introduction: According to a Gallup poll on safety, thirty seven percent of all Americans especially women feel unsafe when they walk alone at night near their communities. There comes the need of a security device which can secretly notify people when they are in trouble. Nimb has as a team of five, Leo Bereschansky (founder and CEO), Nick Marshansky (founder and CMO), Alex Medvedev (CTO), Kathy Romanovskaya (communications director) and Davor Tomic (sales). Leo Bereschansky,CEO and Founder…

Reading is really not my strong suit and an interest of mine, but I became more interested in it when I was able to choose from a list a books that had to deal with music. For my analytic review, I have decided to choose “This Is You Brain on Music: The Science of a Human Obsession” by Daniel Levitin and “Music, the Brain and Ecstasy: How Music Captures Our Imagination” by Robert Jourdain. I have decided to choose these books because I thought it would be fascinating, just from the titles, about…

Tinnitus is the ringing in the ear, which is an unwanted sound that one can hear. The sounds can be constant or comes and goes, soft or loud, and in one ear or both. There are three ways to distinguish the symptoms of the patient’s tinnitus sound: tonal tinnitus, pulsatile tinnitus, and musical tinnitus. Tonal is a near continuous sound that are affiliated with subjective tinnitus, which is just the normal ringing sound, pulsatile is pulsing sound that one hears from their heartbeat and for some…

“It’s not about acting. It’s about giving the art of entertainment to humanity (IMDb).” I will be talking about Sean Berdy. He is a famous deaf American actor (Frost Snow). His deafness never stopped him from pursuing his dreams (IMDb). At the age of 23 he had accomplished his dream (Frost Snow). Sean was born on June 3, 1993, in Boca Raton, Florida (Frost Snow). Berdy was born deaf. Both his parents, Terrie and Scott Berdy, are deaf. As a child, Berdy and his brother, Tyler, would put on…

forms. TV, cellphones, computers, etc. There’s so many different ways we get distracted and it actually wears us down without realization occurring. Having your phone sitting next to you while you're studying, when the snapchat vibration rumbles the table. Yeah, the vibration, you know what i’m talking about. You stop immediately to check it, until 20 minutes later you realize you have to get off of instagram. All of the work you were studying immediately exited your brain and was overtaken by…

travels through. A reed instrument, like a clarinet or saxophone, is an instrument that uses vibrations from a reed to produce its sound. The specific sound is determined by where the air is escaping from the instrument. Both brass and reeds play their instrument by using a mouth piece. These mouth pieces are much different though. In brass instruments, the mouth piece is placed against the lips and the vibration that the musician make with their lips, along with the large amounts of air they…

“Steel plates are commonly attached to each other with rivets, which are slipped into holes in the plates and rounded over with hammers. The hotness of the rivets makes them easier to round over, but their hotness has another important advantage in providing a tight fit. What is it? Explain why.” This relates to one of the characteristics of heat, in that heated objects expand, then contract when the temperature decreases, since the molecules move faster in heat and slow in the cold. The hot…
