Introduction Originating from the streets of Harlem comes a song that, initially, did not gain much fan fair, but went viral on the internet after comedian, Filthy Frank, made a ridiculous dance video of it (Knopper, 2013). Thousands of copycats created different version in unexpected environments such as skydiving or underwater(Allencastre, 2013). The song is called Harlem Shake by DJ producer, Bauuer. These videos popularized a underground, electronic, dance music (EDM) genre known as “trap”.
MIDI for beginners Background The acronym MIDI stands for Musical Instrument Digital Interface. A Musical Instrument is a machine that makes sounds which humans have decided to call music. Digital means information that is encoded in numerical form, i.e. numbers, while Interface means a machine which facilitates communication between two or more systems. In practical terms, MIDI is a standard way for all sorts of modern musical equipment to talk to each other. This equipment commonly
Synthesizers can create all sorts of bizarre noises, from realistic sounding violins and cellos to distorted out of the world sounds almost all programmed by hand. They come in many different sizes, from portable keyboards to humongous mainframes. They are in music, movies, TV shows and just about anything nowadays. Synthesizers are an amazing tool for musicians, with the steep learning curve they come with, can really benefit any one that could understand them. What is a Synthesizer? A Synthesizer
first introduced, people were shocked to see this instrument that could be played without even touching it. The theremin unsually is tuned so that it has a range of three and a half octaves. The theremin's operation is based on the theory of beat frequencies. Two antennas stick out on each side. Usually a vertical antenna is located on the right which controls the pitch. The closer the players hand is, the higher the pitch. A horizontal loop antenna is located on the left and controls the volume. The
Ever since the beginning of time the human mind has been puzzled by the perception of what is now called music. The most primitive sound of the early drums had a very particular effect on the members of the neighboring clans and tribes; who took the drumming as a way of long distance communication among other things. But the most important interpretation of the early music had to do with the effect of making people react to the different moods of this drumming, by combining time and sound it was
Radio Configuration Drones use Radio Frequency (RF) transmitters (TX) and receivers (RX) to send the information used to control the drone. Inside the radio, transmitters encode the digital data from the movements of sticks and switches into an electric current, which gets sent through wires to the radio’s antenna. There, the electric currents generate electromagnetic radiation, or radio waves. Waves with different amplitudes (heights) or frequencies (durations) carry different messages. (FM and
Eric's Wacky World of Words I don't work with small children with any frequency, nor have I been related to any for some years now. I am focusing instead on my own linguistic development, which is in fact rather complicated. I was born in the United States, but raised speaking French. French was my first language, and by all accounts I was a precociously fluent speaker. I learned English more or less in parallel because I needed it to talk to my father, but I used French more often in conversing
and estimating size and shape. • It is sensitive to both surface and surface discontinuities. • Minimum part preparation is required. • It is cost effective technique. • Frequencies associated with relaxation phenomena fall within the range of ultrasonic therefore can be easily focused. In the ultrasonic testing, high frequency sound waves are sent into a material by transducer. The sound waves travel through the material with some attenuation and also reflected at interfaces. The reflected or transmitted
result of interaction of the induced dipole on the cells with rotating electric field. Rotation rate of the cells are frequency dependent, and reflects the cells interior and membrane dielectric properties. The frequency response of the cell can be measured using single cell analyses by electrorotation. In this method, the induced torque is measured as a function of applied frequency.
waves that can send across disparate materials like fluids, soft tissues and solids. It has a frequency higher than the higher human auditory check of 20 KHz.[1] Ultrasound frequency is described as the number of ultrasound waves each subsequent, and health ultrasound mechanisms use waves alongside a frequency fluctuating amid 2 and 15 MHz.[2] The velocity of ultrasound in a specific medium equals the frequency of ultrasound increased by its wave length.[1] Go to: BASIC PHYSICS Medical ultrasound mechanisms
Introduction: Sound is actually a pressure wave; it is produced by a mechanical disturbance in the medium (in most cases- air) in which it is openly adjacent to. After the sound is first produced, it continues to disturb adjacent air particles and causes them to vibrate and hence the vibrations travel to the following adjacent air particles and so on like a chain reaction; however as the sound vibrations travel through the air particles, the vibrations and the loudness of the sound grows weaker and
vibrations of objects. Waves can be measured by speed (v), frequency (f), wavelength (λ), and period. The frequency of a wave describes how many cycles of a wave occur per unit time. A sound with a high frequency has more wavelengths in a set amount of time than a sound with a low frequency. High frequencies have smaller wavelengths, and low frequencies have larger wavelengths. The higher frequency, the higher the perceived pitch. The wavelength, frequency, and speed are all related by the equation: v = fλ
Marine mammals such as dolphins and fish each have a frequency unique to each species, as well as each organism, in a pod.(Baker, 2013) Scientists have called these “signature whistles” Elsevier, 1989). Organisms use these whistles similar to how we use names, associating the frequency to specific individuals in the pod. Whales have a frequency between 40-80 kilohertz while dolphins at about 3-23 kilohertz. Due to the sound differences, organisms are able to distinguish between organisms of
Investigating the Effects of An Abiotic Factor on the Frequency and Distribution of a Freshwater Invertebrate (i) Planning ------------ Introduction ============ Before a complex biological study can be planned and formulated, the terminology in the title above must be clarified. The investigation requires a sound knowledge of ecology, which essentially is the study of organisms, whether they be animals or insects, and their relationship with the environment in which they live
can reproduce are the same quality as a photograph. The frequencies that are used in the archaeological surveys range from 10kHz to 1Mhz. Acoustic imaging can cover a width from several kilometers down to 10 meters. There is a trade off between range and resolution. This depends on the frequency that is being used. Lower frequency models are either ship mounted or towed behind to give a broad picture of the site where the higher frequencies provide a much clearer image. The next method that was discussed
be emitted from a metal by light waves with any frequency as long as the intensity of the light is strong enough, and even if it is weak over a long enough period of time electrons will eventually be emitted. The theory was proved incorrect after experiments showed that light under certain frequencies did not produce the photoelectric effect on the metal, which meant that the emitting of electrons is related not to intensity but the waves frequency. A new string of mechanics, Quantum mechanics, was
traveling in a harmonic, sinusoidal fusion at the velocity of light each possessing a specific amount of energy. The distance from one peak to the next is the wavelength and the number of peaks passing through a fixed point per unit time is the wave frequency (Lillesand and Kiefer, 1994). Electromagnetic radiation is Electromagnetic energy in motion and can be described by the basic wave theory. Electromagnetic Spectrum Electromagnetic waves are characterized by their wavelength location within

Frequency domain filters are used to perceive beats, apply reverb, and add or subtract frequencies. Auditory masking and filtering is used in order to compress the sound file without compromising quality. The beauty of digital audio is mainly reliant on the processing of waves and frequencies. Through further study, more and more compression techniques and
working frequency, resonance and radio waves are all elements needed to power a radio. Frequency means the number of incidence of a repeating event per unit of time. Frequency sends sound signals on a radio wave. FM also stands for frequency modulation. FM and AM are the main chiefs of sending music and words. Frequency receives the name temporal frequency. FM is better than AM. For example, FM is free of static from interferences that affect AM broadcasts and the music of f frequency modulation
Physics Waves Lab SL Introduction: This lab will investigate the properties of mechanical waves such as a longitudinal wave, focusing on the question: Does a change in the frequency of a wave result in a significant and convincing change in the speed of the wave? Hypothesis: Changing the frequency of the wave will not result in a change in speed because the wavelength will change proportionally as in theory. Student Designed Investigation Procedure/ Planning Procedure: 1. Three students
