Acoustic guitar

Speech reverberation is the distortion of the sound by its delayed and attenuated copies. These speech copies originate from the reflections of surrounding walls or objects. This phenomenon of reverberation reduces speech intelligibility and degrades the performance of hearing aids and Automatic Speech recognition (ASR) systems [1]- [4]. The resulted speech distortion can be contributed by two distinct components of reverberation - the early reflections which cause the coloration of speech, and…

Figure 2 demonstrates the variation of positively compensated admittance (Ytm), susceptance (Btm), and conductance (Gtm) as a function of probe tone frequency. While acoustic resistance is independent of frequency, acoustic conductance does vary with frequency. The variation of Ga with frequency can be understood as a variation of Ra and Xa with frequency. Stiffness and mass susceptance are frequency dependent. Mass susceptance is directly proportional…

Ultrasound Technicians, also known as diagnostic medical sonographers, use equipment that makes sound waves to produce or record a picture of the internal organs. Sonography is an important medical field because it allows technicians and physicians to see and diagnose a patient’s condition in a minimally intrusive way. What once may have required exploratory surgery now is a quick outpatient procedure with minimal patient discomfort. Ultrasound works by using a high rate of sound waves and…

You hear many sounds throughout the day. In the morning, the sound of your toaster, when your pop tarts are ready. At night, when your floor squeaks when you go to the bathroom. There are many noises throughout your day. The poem “Atoms of Sound” is about everyday noises are what form your days and nights. Throughout your day you hear many noises. The television turned up; chitchat on the telephone (lines 9-10). You can also hear your dogs. Their long claws clicking on the floor (lines 4-5).…

spastic and flaccid dysarthria (1, 22-24). The studies compared the perceptual and acoustic findings with instrumental measures and found similar outcomes, hence validating the reliability. Perceptual-based descriptions included imprecise articulation, reduced speech rate and breath support, reduced pitch and loudness variation, increased nasality, and strained-strangled vocal quality. (21, 23, 25, 26) Acoustic-studies revealed prolongation of syllables, vowel and speech segmentations and…

Sound. Another complicated, complex idea humans struggle to completely understand. Sound is highly difficult to understand and explain. It is difficult because sight overpowers hearing. Additionally, sound is difficult to explain because it is affected deeply by different experiences, such as: Berine Krause’s personal experiences in his “First Notes” article. Also, sound is very different and unique which makes it hard to fully understand. The “First Notes” article and the passage from “Sound as…

1) What are some possible correlates of phonological and articulatory impairments? These disorders are not promptly available, in some cases the causes are unknown. The correlations can occur together, or in some cases one is not necessarily caused by the other. Some of the possible factors of phonological and articulatory impairments can be developmental impairment in speech-sound production, language impairment in their production of sounds of the language, hearing impairments which enable…

Oblivion, off their album they just came out with. I really started paying attention to guitars when the guitar player, Brent Hinds, brought out his see through Flying V guitar. It was one of the most amazing guitars I had ever seen. I left that night feeling pretty good. For it being my first ever concert, I was amazed that you could do so much more with just 5 instruments. It got me on a mindset of playing guitar. A year later I went to another concert in St. Louis. I saw Cavalera Conspiracy.…

Folk music has a very wide description and can be created in many forms. Folk music just as Folklore is typically passed down orally from generation to generation. Because of this one song may have many different versions and is typically short because of forgetfulness from being passed down. It also typically has an unknown artist so a lot of folk songs are not by the artist him/herself. One criteria is folk songs are that their short, this is because of the forgetfulness of the song being…

challenges by expanding. Sawchyn Guitars was founded by Peter Sawchyn in 1970. It was a small private business solely owned and operated by Peter Sawchyn and his wife Kendra Sawchyn. The company deals with two main products: acoustic guitars and mandolins. (Woodwark, Wong, p.2). All the models of guitars and mandolins could be custom ordered, repaired and upgraded per customer’s precise needs. The founder of the company Peter Sawchyn had 40 years’ experience of making custom guitars and their…
