Project Report from the year 2016 in the subject Physics - Acoustics, grade: 3.56, , language: English, abstract: This study was carried out in order to investigate the noise level at the Ondo State School of Health Technology, Akure. Prospective study design was adopted for this study and noise level meter was used to collect data and simple random sampling technique was used. The school was divided into 4 sections which are Academic, commercial, administrative, and residential sections and a sample size of 100 was determined, the retrieved questionnaire were sorted and analyzed using tables and bar charts. During the course of sampling with noise level meter, it was noted that noise coming from the commercial section was higher than any other section and ranged between 80dB and 89dB which is above the threshold limits man can be exposed to due to the operations carried out in the section. However, at night it was measured to be at lowest level of 49dB based on the close of commercial activities around 7pm daily. In the residential section it was noted that the level of noise produced between the hours of 10am and 1pm was the lowest but from the hour of 2pm upward the noise was at its peak based on the presence of the student in their various lodge ranging between 65dB to 79dB at the academic section the noise level range between 45dB to 60dB which means that the noise levels is low at the section. In the administrative section, the noise produced was between 45dB and 50dB which means that the noise level was at the lowest level for the entire school environment. In the questionnaire people´s knowledge and perception was measured, sorted and analyzed which shows that noise level is high at the ondo state school of Health Technology which should be minimized to enhance a good and conducive environment for learning/teaching.

Oil power transformers are an integral part of electrical power systems. The main cause of failure of such transformers are damages to the insulation system caused by the harmful phenomena of partial discharges (PDs). Examination and diagnosis of PDs in oil power transformers (necessary for safety reasons and for economic reasons) includes their detection, measurement and location. The acoustic emission method (AE) provides such possibilities. The book contains selected works from this subject published by the research group from the Silesian University of Technology in Poland. Within individual chapters there are presented applied/constructed measurement systems and analyses of recorded signals in domains of time, frequency, time-frequency and discrimination threshold. As part of the analysis in the domain of discrimination threshold, the authors defined descriptors with the acronyms ADC, ADP and have proposed patented research methodology allowing for determining descriptors maps on lateral walls of the tank of tested transformer. Such calculated descriptors maps in selected frequency bands are the base for the location of the various types of EA wave sources, especially for PDs.

(Acoustic Resonance Enhancement) is an original wood reforming technology developed by Yamaha. Through precise controll of temperature, humidity, and atmospheric pressure, the molecular properties of the wood can be manipulated into a more acoustically ideal condition, similar to the molecular characteristics of woods in instruments that have been played for years. In NX Series guitars, this treatment results in a sound close to that of a vintage guitar that has been played for years. It produces a sharper tone while simultaneously controlling dissonance in the high range. Instruments that have undergone this process have received high marks from a great number of musicians. Their evaluations are nearly identical to those for guitars that have been played for years, and their comments often include terms such as well settled, mature, warm, excellent resonance, and clear.

Hard and strong it is often used for necks on electric guitars. When used for backs and sides it produces a crisp, clear, less resonant tone that cut through well making it great for lead playing.
