Acoustic emission

The music was blaring. It sounded like the music of a late nightclub. I couldn’t focus. I’ve never been a good multitasker. It’s impossible to listen to music and write an essay at the same time. My eyes glanced to the side to check Mira’s half of the dorm. Of course, she wasn’t there. The noises were coming from the floor above me, where the large dorms were; they were for the wealthy, privileged students. Every Tuesday the guy above me would throw huge frat parties, and somehow not get in trouble

The normal range that humans are able to hear from is 20 hz to 20kHz. The average human can hear up to 20 hertz, After using the resources provided in Physics class I discovered I can hear between 19hz and 20hz. I could sometimes hear the 20hz but sometimes I could not. I am about average for the highest frequency I could hear. Sound is made of pressure waves which when they travel oscillate or vibrate. Each wave travels at a certain frequency based on how much the sound moves. Sound is created when

The purpose of this email is to inform you of a concern that we, the tenants in Unit #4 at 2332 Saidel Drive, have regarding a noise issue from Unit #3. For quite some time, we have been hearing a loud, whirring, and humming/vibrating noise coming from this unit.  Not only do we hear it through our walls and the bathroom, but also our bedroom, which makes it very difficult to get a restful night’s sleep.  We have tried wearing earplugs and even create white noise, but it does not drown it out or

Soundsuits are sculptural forms that are based on the scale of the body. The soundsuits disguise the body, masking and creating a second casing or membrane that conceals race, gender, and class. The inspiration behind the soundsuit from Orlando Museum of Art’s was looking at the status of the world where people are judged by how they look, their skin color, the type of clothes they wear or whether they are male or female. Nick Caves’ aim was to remove judgments in the world and create an atmosphere

Matilda Ultrasound What is an ultrasound? An ultrasound is a medichal test that uses highfrequency sound to capture live images from the inside of for example your body. The ultasound is similar to sonar and radar wich helps the military detect planes and ships. Ultrasound doesnt’t use any radiaion (unlike other imaging techniques) so it’s the preferred method for viewing a developing baby during pregnancy. Who invented this? The ultrasound was first tried on patients 1958. Ian Donald

Maximum Phonational Frequency Range (MPFR) is described as the maximum range of phonation between a client’s lowest modal/chest register tone and highest loft tone/falsetto register. The MPFR is typically determined by using a pitch – matching procedure. Ms. Noid will be instructed to sustain a vowel (i.e. /a/) matching the pitch of a presented tone (i.e. sine wave). She will start phonation at a comfortable frequency level, and will incrementally increase her frequency range production, until she

According to the acoustic theory of speech production, what we know to be speech output results from a source of sound energy (e.g. the larynx) modulated by a transfer (filter) function which is determined by the shape of the resonator (vocal tract). This model, often referred to as the "source-filter theory of speech production," originates from the works of Gunner Fant (1960, 1980) and Stevens and House (1955, 1961) (Haskins Laboratory, Yale University 2008). Source filter theory puts forth two

Any beautiful morning could be accompanied by the sounds of birds chirping, dogs barking, or owls hooting; however, is this just sound, or is this a way of communication that we simply cannot understand? Are animals communicating with each other or are they simply expressing their feelings and instincts? One would find that what may seem like just background noise is much more complex than originally thought. Of help prove this argument, three articles were collected which go into detail regarding

I needed to amplify the sound waves of the song "I am a Believer" using a two liter bottle. In order to achieve my goal of playing this song clear with, no fuzziness, and no echo I had to look at my materials. I chose water because the sound waves will resonate off and not absorb into the water, and then the sound waves will exit through holes that I cut into the bottle. The materials we used to make this sound amplify is a two liter bottle, an iPod, and water from the sink. One lesson in particular

To fully understand how to determine the velocity of sound in air, many concepts have to be understood prior to the experiment. Sound waves transmitted through a fluid are a type of longitudinal wave. These mechanical waves are formed when energy passes through a medium and moves particles in the same direction or parallel to the energy. The particles move in a series of high pressure and low pressure regions. The energy will compress some areas of the medium, creating a high pressure region
