Not all reproduced sound is originated in an acoustically designed environment and therefore does not contain high quality reverberations. And, even when an acoustically designed environment is used, high quality reverberations which are perceptible by the human ear may get lost in the recording process, for instance if the sound converting equipment (e.g., a microphone, etc.) is unable to register them. In addition, some reproduced sound originates in environments which produce low quality reverberations. Sound reproduction systems have been developed to remove these low quality reverberations. However, in their effort to clean up or remove the unwanted reverberations from the audio signal, desirable or high quality reverberations may be partially or completely removed.
Another problem with reproduced sound, such as music, is that it can become distorted when heard at high volumes. It is often difficult to clearly hear the words being sung in a song or distinguish one musical instrument from another in a piece of music.
An additional problem is that the quality of the reproduced sound can vary depending upon the geometry of the room in which the sound is heard and upon where the listener is located with respect to the source of the reproduced sound (i.e., the speakers). Typically, when this occurs, there will be one or more specific locations of higher quality, often referred to as sweet spots. Thus, in order to enjoy the full potential of such sound reproduction systems, a listener is forced to remain at these sweet spots.
Various systems, a number being very sophisticated and expensive, have been developed in an effort to produce an enhanced electronic audio signal which, when converted into audible sound, is perceived as more closely duplicating the experience of hearing the original live sound.

Many measures, such as electrical impulses, acupuncture, presbyopic glasses and vibration massage, have been tried for myopia prophylaxis and therapy in order to get rid of the inconvenience and suffering caused by myopia.
