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…

The photo on the right shows a medical technician using an ultrasound machine to diagnose appendicitis to a patient, without the use of x-rays. The ultrasound imaging technique involves using high frequency sound waves and their echoes. The machine transmits high-frequency sound pulses into the patient’s body using a probe. In the image, the technician presses and moves the probe along the patient’s body. This photo was taken in the St. Louis Children’s Hospital, and obtained from *. In terms…

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…

Introduction The acoustic reflex (AR) describes the involuntary contraction of the stapedius tendon in response to high-intensity sound (Emanuel, 2009). An intricate neural network, receiving afferent input from the vestibulocochlear nerve and sending efferent output to the facial nerve, controls contraction (Emanuel, 2009). The reflex is intensity-dependent, as particular intensities cause the contraction. Once contracted, it lessens the vibrations traveling through the stapes footplate as it…

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…

and attributed into distinct perceptual streams analogous to the distinct sound sources in listeners’ environment (Bregman, 1990; Moore & Gockel, 2002; Carlyon, 2004). The process with which the nervous system makes sense of complex patterns of acoustic stimulation is called auditory scene analysis (Bregman, 1990). Thus, segregating the sounds arising from various sources in the environment, leading to an internal representation of auditory streams becomes the goal of auditory scene analysis.…

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…
