ABSTRACT: Noise is the unwanted sound. With the development all around the sources of unwanted sound are increasing day by day by knowingly or unknowingly. Hence the noise monitoring at two silence and two commercial zones in the Visakhapatnam city was carried out. The locations for Silence zone were ‘Sri Shanthi Ashram’ and ‘Biodiversity Park’ and for Commercial zones were ‘Purna Market’ and ‘Dabagarden’. The results show that the equivalent noise levels are higher in the both commercial zones

The Bose Cinemate 15 has continued to enjoy rave reviews since its introduction to the market. It has gained traction with its compact form, powerful sound output and its glossy feel. It is one of the best buys that can help to keep your space full of excitement. There are some features in the product that make it stand out. However, it is essential to understand some basics before dig deeper into the technology behind this device. This product comes in form of a sound bar. This simply means it can

For wireless underwater communication, there are several means such as radio waves, optical waves and acoustics. Radio waves: Radio wave has extra low frequency (30 Hz–300 Hz) and it works well to propagate any distance in sea water. But, for its low frequency, it is needed high transmission power and large antennas. Optical waves: An optical wave for wireless

The paper illustrates the differences among individuals in the Frequency-following response (FFR) and its connection with pitch perception. Generally, the FFR is presumed to introduce the pitch of a particular sound perceived by individuals. FFR varies among individuals and the reason of this variability is still unknown. However, the authors of this paper carried out the investigation to find out the relation between FFR representation of the frequency of a complex tune and perception of the pitch

Ultrasonography is an important type of diagnostic testing method that is used all around the world today in mostly hospitals and gynaecology clinics. The Wikimedia Foundation states, “It is used to see internal body structures such as tendons, muscles, joints, blood vessels, and internal organs” (“Medical” par. 1). Therefore, the use of ultrasounds can evaluate these specific parts of the body. X-rays can not evaluate the internal organs of the body. As BBC states, “Compared to x-ray photographs

This study was designed to determine a) how psychosocial factors affected subjective and objective measures of vocal fatigue, b) if and how these outcome measures changed pre-post vocal exertion evaluated through the adapted LingWAVES protocol, and c) if there was an effect of education or employment on some of these variables. In this study, all participants were female, and this could have been due to the high prevalence of this gender in the field of speech-language pathology. According to the

There were full of environmental sounds around the Fort Snelling State Park. I recorded the sounds for about 5 minutes and I could hear a lot of sounds I can imagine and reconsider the soundscape and landscape of the Fort Snelling State Park. There were sounds of winds, several different kinds of birds, water, grass when I stepped on, and even sounds of breathes. The Fort Snelling State Park is located in the center of Twin Cities and it is really close from the MSP airport. It is also right next

In my life, cacophony is all around me. When me and my family watch sports on the TV there is a lot of hubbub when the team we are rooting for scores or makes a good play. It also happens during one of the many hockey and lacrosse games that my brother or I play in. Cacophony is all around me when I go to a crowded city or store. It affects me in many different ways, some worse than others. I can either handle it really well, or get a pounding headache and become disconsolately until I get away from

An ultrasound and magnetic resonance imaging, more commonly known as an MRI, are two common ways doctors obtain pictures of what is happening in one’s body. An ultrasound uses soundwaves to penetrate human flesh. As these waves encounter things of varying density in the body, the waves are reflected back differently. Due to these waves’ reflections, the ultrasound machine can formulate an image in real time, and physicians can interpret these pictures to give diagnoses (No Author, 2008). On the

The article “ Feasibility of Group Voice Therapy in Individuals with Parkinson’s disease” by Jeff Seal, Kristel Wilson, Karen Haring, Angela Dietsch, Kelly Lyons, and Rajesh Pahwa sought to test the likelihood of increasing speech loudness levels in individuals with PD through group-focused tasks. The LSVT-certified Speech Pathologist and graduate students who conducted this study mimicked the Lee Silverman Voice Treatment (LSVT) as closely as possible to test patient’s loudness levels in the group
