Audio equalizer is a useful device that will boost the sound system of your home theater. It is commonly used at home to create a theater like entertainment room and also on cars as a stereo system. The advantage of using an audio equalizer lies in the manipulation or control of the frequency according to your preference. So you can conveniently take control of the tone on a more precise levels compared to bass and treble controls.
The audio equalizer contains a level of adjustable equalization wherein it electronically alters the frequency balance of the music sooner than it is played on the loudspeakers. Usually users set the equalizer in a smile shape curve with both ends at higher and steeper level that gradually flattens towards the middle section. The smile curve is a reasonable method of equalization adjustment.
Although the audio equalizer can boost the sound system capabilities of your home theater, there are other problems concerning its use that you may want to consider before purchasing or using one. This article presents to the concerned reader the 3 common home theater audio equalizer problems. This is not to discourage people from using an audio equalizer but just to inform them of possible problems they will encounter soon.
Problem #1 - Limited Room Effects Distortion
Most people wanted to use the audio equalizer to change or improve the quality of sound and produce sound effects within the home theater room. Rooms do certainly influence the frequency balance on the listeners. The catch is that there are specific room effects that exists within the perimeter of that certain room therefore distortions resulting from audio equalization varies from one listener to the other. Listener A may hear differently from Listener B who is a 2 feet away from the A. Thus, changing the audio effects using the equalizer within the home theater room will only be favorable to one listening area and leave the other listeners in a poor listening situation.
Problem #2 - Poor Vocal Clarity
Dueling remote control effect is a common scenario that usually happens in home theater rooms and even with an ordinary television setup in the living room. This transpires when a person immediately increases the volume of the audio whenever he or she has difficulty assessing the conversation, thinking that the sound emitted from the television is simply not loud enough.
Listener A may be the person who turned the volume up while beside him or her is Listener B who is annoyed with the loud voice and has no problem absorbing the conversation exchange of the characters in the television. You may evaluate Listener A as a person experiencing the symptom of hearing loss; it can also be a result of audio distortions caused by room effects. Vocal clarity can be affected once the audio system is distorted or somewhat absent in that area where Listener A was. Thus, audio equalizer on this situation will only make the problem worst if it will be adjusted.
Problem#3 - Smile Curve cannot Improve Room Effects
Human ear can perceive sound best in an area where the human voice falls. During the early 20s, hearing starts to drop thus we may have poor bass perception and the uppermost frequencies as well. So if you use the smile curve method to improve the room effects that would be useless. Instead it should be maximized to correct the aging ears of the listeners.
