Radio frequency

17. What is the frequency range of human hearing (in Hz)? (1 point) Answer: The human range is commonly given as 20-20,000Hz. Although there are some differences between individuals. 18. Explain the difference between Gain Change and Normalization, providing an example…

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…

Link between music and musical notes The link between music and notes is very similar as the slower the vibrations the lower the frequency of a note (Carson. B, 2014). So when you hit a high note the sound is quick and fast for example a triangle the frequency is low (Carson. B, 2014). However when you hit a lower note it is slower such as a base drum the frequency will be…

This is a very frequently used modality in the many athletic training rooms. This modality mainly used in the athletic training setting as a therapeutic agent and not a diagnostic tool. Ultrasound uses acoustic energy at high frequencies. The goal of this could be to achieve thermal or non-thermal physiological effects. In this case review ultrasound was used as a non-thermal healing agent. This acoustic energy is caused by an electrical current that causes the mechanical vibration…

As we discussed phonological acquisition in bilingual children by reading Tessier chapter 5, and Vihman 2016, I became more curious about bilingual children’s phonological acquisition and its acquisition process. As the discussion of whether the bilingual children have two separate phonological system at the begging or not has been a big question in the study, I wanted to have further reading on that topic. This paper, “Phonological Acquisition in in Bilingual Spanish-English speaking children”…

with the study of sound. Sound is a wave made of vibrations in the air. Waves can be measured in a range of different ways: by their amplitude, wavelength, frequency, speed, and, at times, their phase. Sound information is transmitted by the amplitude and frequency of the vibrations, where the amplitude is experienced as loudness and frequency as pitch. The vibration is started by some mechanical movement and this causes a vibration on the molecules next to the mechanical event. When these…

In sound waves, high frequency coordinates with high pitch, and low frequency coordinates with low pitch. Wave Interference Wave interference occurs when two waves meet while traveling along the same medium. There are two main types of wave interference. Constructive interference is when two waves…

The earliest of studies for speech sounds has been studied intensively since the early 1930s. Studies concerning the acquisition of phonemes are used in clinical practice and serve as a guideline to a practicing clinician. The earliest of studies came from 1931 by Wellman, Case, Mengert and Bradbury. Following Wellman’s findings, other researchers found new material and listing different ages in comparison to Wellman’s research. Sander (1972) discusses the various individuals that contributed to…

I snap my fingers and the air around me shifts then vibrates. When the air vibrates, it creates a sound wave. Our ears pick up this wave and translates it so we can understand and comprehend what amazing intangible creation is before us. A middle C key is pushed on a piano, the hammer hits the tuned wire, the wire vibrates and creates the sound humans recognize as a simple C. As time has passed, humans have progressed from single note instruments, to handwriting sheet music for orchestras, to…

This artifact is primary based on sample rates and to see the effects of sample rates by using Sinusoidal waves. Sinusoidal waves can be represented using frequency and period. The Frequency of a Sinusoidal wave is the number of complete cycles that happen in a particular period of time or in a given sample. The Period in terms of Sinusoidal waves, is the time it takes to perform one complete cycle. The Sinusoidal wave is a series of identical cycles happening repeatedly. The sample rate is the…
