A cardboard is a moving part of the given hand made microphone. When a sound wave strikes the diaphragm (cardboard in the following experiment) of the microphone‚ the diaphragm vibrates back and forth‚ and the attached coil moves along with it. Additionally‚ magnet is attached with coils on a cardboard. When the coil alternately approaches and move back from the magnet‚ the flux through the coil changes. As a result of this‚ an ac emf is induced in the coil. Next‚ this electrical signal is sent to

MONITORS On-stage monitors are really important as they allow the musicians on stage to be able to hear themselves clearly. There are different types of on-stage monitors that suit different needs. Passive stage monitors have external amplifiers and are less costly to replace if they fail‚ as the power amp does not need to be replaced if only the monitor fails. Passive monitors are often preferred for venues with installed sound systems. Powered or active stage monitors have amplifiers built right

I used a Behringer ECM8000 microphone to measure the control rooms. I measured with The Eurodesk’s Genelec 1031A loudspeakers and the Neve’s Tannoy FSM in-wall loudspeakers. For the measurements I placed the ECM8000 in the listening spot between the loudspeakers in a triangle equal distance between the loudspeakers and the microphone and use the SPL meter the measure a level of approximately 85dBSPL. I used a stimulus signal

Different methods of communication 1.0 Introduction Communication can be considered as one of the most important parts of human life that has evolved during the history of our existence. Different methods of communication from smoke signal to sign languages to face to face communication have played an important part in our lives. Rapid development in the technology field caused evolution of electronic communication and we started to develop better and faster tools and methods to communicate with

The manager deliberately invades her employees’ privacy by installing microphones in the restroom‚ stockroom‚ and employee lounge. The microphones are an invasion of privacy because Fanuchi’s actions begin to cross the line that constitutes personal privacy‚ and this becomes unfairly prejudicial to the employee when they are caught saying something that inculpates

thunder-like voice‚ was used primarily before microphones (150). With the introduction of the microphone came the crooning style of speech‚ which had a quieter calmness to it. Each have their place and each are media for bringing about different responses. In the case of spellbinding‚ gestures such as clenched fists and stamping feet convey specific emotion. Visual and sometimes physical contact were just as important as verbal contact because before the microphone it might have been the only way for a

Microscope ‚ Telescope ‚ Periscope and others. The range of frequency of hearing in human is from 20 Hz to 20000Hz. It is different according to the age of a person. Limitation of hearing can be overcome by using appropriate hearing aids such as microphone‚ stethoscope‚ amplifier and others. Function: A microscope is an instrument used to see objects that are too small for the naked eye. Telescope Function: A telescope is used for viewing distant objects like stars‚ planets‚ the moon and others

absorption‚ a system for active impedance control has been developed‚ so far for plane waves at normal incidence. The active reflector is a loudspeaker driven by the incident sound wave. Its feeding signal is derived from a "wave separator" with two microphones splitting up the standing wave field into incident and reflected wave. This system permits easy control of the reflection coefficient and eliminates feedback instability. Arbitrary reflection coefficients between almost 0 and about 1.5 have been
