1. Explain the difference between periodic and aperiodic waveforms. What are the visual differences? What are the characteristic sonic qualities of each? (2 points) Answer: A periodic waveform has repeatable patterns. Also, periodic waveforms have a tone. Most musical instruments have repeating periodic waveform. The periodic waveforms can also be found in bird sound and human vocal voice. However, an aperiodic waveform dose not have a repeating waveform and tone, like noise, the engine idling…

Assessment Gillam, S. L., & Ford, M. B. (2012). Dynamic assessment of phonological awareness for children with speech sound disorders. Child Language Teaching & Therapy, 28(3), 297-308. doi:10.1177/0265659012448087 Introduction: Gillam and Ford created a dynamic assessment to observe the associations concerning performance on a nonverbal phoneme deletion, word-level reading, and speech sound production that require verbal responses for school-age children with speech sound disorders. The…

did u know that sound is energy and how sound work? Read more to find out how sound is energy and how sound work. Sound is a release of energy the energy is released in the form of vibrations . How sound work is the vibrations emit from whatever has made the sound in what is known as a longitudinal wave.A longitudinal wave is a wave that travels in a single direction. Next how can we hear sound. We can hear sound from a longitudinal wave for example when a tree falls and energy is released…

Client’s Name: Amanda Client’s Age: 49 Disorder: Dysphonia and Vocal Fold Nodules Observation #1 Amanda is a police officer, and her responsibilities include frequent speaking engagement in which she must speak a lot of ambient noise. In addition, she has smoked a pack of cigarettes a day for 25 years. Amanda was referred to a speech pathologist for evaluation of her voice. An examination revealed an abnormal change in the voice, or dysphonia, most likely bilateral true vocal nodule on the…

Instrument- .Glass bottle xylophone My experiment is about making a Glass bottle xylophone that plays six notes What is sound and how does it travel? Sound is a sort of energy made by vibrations (Jane. E, 2016). When any object vibrates, it causes movement in the air particles (Jane. E, 2016). These particles bump into the particles close to them, which makes them vibrate too causing them to bump into more air particles (Jane. E, 2016). This movement, called sound waves, keeps going until they…

In this particular episode of the podcast, 99% Invisible, Roman Mars explores unpleasant design, and how architecture and technology have contributed greatly to the depersonalization and sterilization of public spaces. One of the original methods of deterrence through design is sound, more aptly put, sound that is unpleasant or assaulting to the ears. The best example of this is something I myself heard about but never experienced (thankfully) throughout my adolescence. In an attempt to combat…

At some point in time, many people will experience problems with their voice. When speaking, words may sound broken, whispery, strangled or hoarse, and a person may struggle just to sound normal. In most cases, these vocal problems eventually go away, but if they don’t, then this condition may be a neurological disorder known as spasmodic dysphonia. Definition and Facts Dystonia is a neurological movement disorder that can affect the entire body or a specific body part. The primary…

the assignment of writing an essay on mass production. We had to select one thing that is mass produced, and write a very detailed five paragraph essay on it. I am a major fan of all things that make music or all things that make noises, I chose acoustic guitars. While I researched how guitars are mass produced, I thought that the history was pretty interesting, along with where and how they are made. Body #1: As I mentioned earlier, I think that the history of guitars is pretty interesting,…

prefabricated parts. Most people, however, would feel that the best guitar is made by hand, where every grain of wood is analyzed, to ensure the perfect sound quality. An acoustic guitar is built with the right wood patience and a unique understanding of how wood works and the basics of acoustic sound will enable the creation of an acoustic guitar. The guitar’s history is very vague. The guitar has many ancestors like the lute, the stringed bowl, or the kithara. Guitar is defined by Dr.…

Acoustic Transponders Three main acoustic positioning systems (Fig. 3) used for localization of AUVs are introduced and discussed. They are short baseline (SBL) systems, ultra-short baseline (USBL) systems and long baseline (LBL) systems. The transponders of SBL and USBL systems are deployed on a anchored ship or pier before the start of mission. LBL systems require transponders to be mounted on the seafloor before localizing AUVs. These three acoustic positioning systems are stated as below. 1)…
