		Live chat support service also gives you vital information about how consumers got to your site, how long they've been there, and where exactly they committed to buy or decided to bail-giving you new insight into what is and isn't working with your website.
		Even though live support service is flexible enough to fit any support service, whether technical, sales or information-based, choosing the one that fits your needs can be a time-consuming task.that's where we can help.
		Live Chat Customer Convenience – Little conveniences make all the difference to a customer, like knowing their question is receiving attention even before the live chat operator sends the response (typing indicator).

		Feedback occurs when sound from the speakers finds its way back into the microphone and is then re-amplified and sent through the speakers again.
		During concerts, something called live sound reproduction systems are being used.
		At a concert in which live reproduction is being used, it often times is necessary to have manufacturers, sound engineers, and sound companies on site due to the use of complex sound systems.

		Sound Reinforcement is also the name applied to an entire industry that involves manufacturers, "Sound Engineers" and "Sound Companies" If you see a live concert, these people are usually involved.
		What they do is considered "sound Reinforcement" but contrary to the above mentioned definition it is very obvious, Especially for poular music where the PA system is very obvious and generally all you hear and feel.
		A "PA" (an acronym of "Public Address") is a usually simpler design that just amplifies the initial sound and it will be obvious to the user that it is being used.

	The widespread acceptance of home audio in recent years has led many consumers to bypass learning the basic principles ...
		However, there is only one true standard for high fidelity sound reproduction: what the human ear and mind perceive as a natural and credible recreation of the live performance.
		There are four basic factors that distinguish one sound from another: (1) frequency, or rapidity of vibration; (2) volume, or intensity; (3) timbre, or sound quality; (4) duration, the length of time that a sound persists.
		The sound you hear from a TV, an AM radio, or through a telephone is monophonic as there is only one signal or, more commonly, one channel of sound.

	Live sound reproduction - Wikipedia, the free encyclopedia
		A "sound reinforcement" system enhances the volume of the initial sound and will be designed so that as much as possible the listener will not realise that an artificial system is being used to make it easier for them to hear the initial sound.
		A "public address" (PA) system is a usually simpler design that just amplifies the initial sound and it will be obvious to the user that it is being used.
		PA systems require a microphone, an amplifier of some kind and a loudspeaker and can range in size and complexity between handheld (megaphone) or requiring several large trucks to move.

	Sound Reproduction
		In the case of a live event, we perceive the artistic performance as it is influenced sonically by the hall or auditorium and its acoustics, by our own state of being, by the response of the audience, and by our physical location within this environment.
		It is difficult to describe the quality of a sound reproduction system in words, unless there is some agreement on the vocabulary.
		Besides, the sound of the piano is nothing like what I am familiar with when the stereo microphones are placed under the lid, close to the strings and then fed to left and right channels.

	Audio Engineering Society - Chicago Section - Meeting Review, May 6, 2003
		Careful consideration was made of the difference between the sound field sensed at the outside of a blocked ear canal versus that at the eardrum when the canal is open, and it was shown that the frequency response of this transfer function is quite independent of sound field direction.
		Live and pre-recorded demonstrations were conducted to evaluate the technique and to show how visual and other non-auditory cues affect directional sound perception.
		The live demonstrations generated enthusiastic discussion, and were special in that each audience member was able to experience binaural reproduction first-hand.

		This affects sound quality and component life (especially the transistors), and is to be avoided.

	Schertler USA - high fidelity acoustic transducers, speakers, mixers & velvet strings
		The heart of the transducer is a coil which moves through a decoupled magnetic field to create a voltage differential, delivering a true response to the acoustic vibrations of the instrument’s body.
		The sound is close to that of a studio microphone, but without the on-stage problems of bleed or feedback.
		The practical use of a solid-state transducer for live applications depends on the elimination of feedback and bleed.

		A fixed plate acts as one side of the capacitor and changes in sound pressure acting on the diaphragm -- a thin membrane -- and alters the circuit's capacitance and therefore electrical output.
		That is not ideal in a live performance application, so vocal mics will typically be directional, picking-up sound mainly from the front and canceling sound from other directions.
		For studio and live use, its high SPL capability allows the microphone to be placed close to loud sound sources such as kick drum and bass guitar or it can be used for vocals, brass and woodwind instruments.

	The DJ's Unique Needs
		For live-sound reproduction in which vocals are involved, compression driver/horn combinations for the midrange are the norm because of the extra output requirements of the voice in terms of output and focus when competing for volume with other instruments in most combo or band applications.
		Many horn design variations that sound quite natural have become commercially available, and in larger spaces, the driver/horn is the optimum choice purely because of economics and ease of serviceability.
		Make your client aware that he or she can live with a conventional number of subwoofers when they are properly coupled with good placement in the club.

	U.York : MTG: Ambisonics Home Page
		Sound from a source to the left of the head, for example, will arrive directly at the left ear, but will have to travel "through" (!) the head - actually it is diffracted round - to get to the right ear and will also have to travel further.
		The Ambisonic surround sound system is essentially a two part technological solution to the problems of encoding sound directions (and amplitudes) and reproducing them over practical loudspeaker systems in such a way as to fool the ears of listeners into thinking that they are hearing the original sounds correctly located.
		Reproduction requires four or more loudspeakers depending on whether it is pantophonic or periphonic, size of area etc. Practical minimums are four for horizontal only, eight if you require height as well.

		Amplifying sound and delivering it pleasantly and effectively to the ears of an audience-this simple objective known as sound reinforcement is in some ways the most basic task in all of the various audio fields, yet in other respects can be among the most difficult to accomplish in actual practice.
		The only thing in Live Sound Reinforcement that wasn't in The Live Sound manual that I found useful was the one page on 'ringing out the room' to address feedback before it happens.
		In short, if you have taken courses on sound, or are very knowledgable this book isnt for you, but if you want know how to wire a full concert PA system will all the works, this book is for you...

	Shavano Music - Adding subwoofers to your PA system
		They don’t have stacks of speakers and amps stacked to the ceiling behind them; they make their sound with relatively modest equipment and the PA system, which is the size of a suburban house, carries it throughout the arena.
		Even though subwoofers only reproduce a limited range of sounds, the physics of sound dictate that they be large and heavy because the lowest sounds are the most difficult to reproduce.
		It was discovered long ago that a sound source can be louder and more resonant if attached to a cone, or horn, that concentrates the sound waves and keeps them from diffusing into open air.

	Audiomixers: in houses of worship
		To understand the needs of the modern worship system, we must first identify the three primary jobs that a mixing console is called upon to perform: live sound/voice reproduction, fold-back/remote monitoring and recording.
		The traditional use of zone miking techniques and reverberation effects to enhance the sound of a soloist or choir are still widely practiced, but many applications require multiple inputs from handheld mics.
		There are times, however, that for effect one may wish to mix in the sound of the congregation or even create a separate individual mix totally independent and unaffected by the main system mix.

	Why acoustic music Live Engineer - PA Sound System Training Courses
		Very often, excellent acoustic artists can have their concert ruined by "rock-and-roll" sound engineers who simply aren't used to dealing with the intrinsic nature of acoustic music.
		Precise and attentive engineering is required to avoid feedback and obtain a good sound both on stage and in the concert space.
		By developing an engineering skill-set in acoustic music, it is possible to translate those skills to other areas of live sound reproduction.
