Relax and enjoy: ‘Home-Theatre’ is the buzzword these days.

The digital revolution has taken the entertainment industry by a storm. With each passing day, wider and higher resolution television sets are being launched in the market. This trend is sure to change the way you experience entertainment. You can now have the experience of a theatre at the comfort of your home. ‘Home-Theatre’ is the buzzword these days. A high resolution television, a multi-channel music system and plush furniture are not the only requirements for a home-theatre. Due consideration should be given to the acoustic performance as well as to the light present in your would-be home theatre room.

The acoustic efficiency of your home theatre is very critical for a clear and optimal home theatre sound. No matter how good your home theatre sound system is, if the room is not designed properly for good quality sound, it will simply sound terrible. The room’s construction, furnishings, widows, and wall surfaces, all have a massive impact on the acoustic performance of your home theatre.

Hard surfaces like wooden or ceramic tile flooring, gypsum partitioning and concrete ceilings, etc., cause a high level of sound-wave reflections thus leading to echo and poor sound quality. On the other hand, soft surfaces like carpets and wall-to-wall curtains absorb most of the sound waves and make the room dull and lifeless. For a lively and clear sound quality, try to strike a balance between these two types of acoustic surfaces.

As a thumb rule, make up to half of the total room surface area - wall, ceiling, and floor area, absorptive. Most of these absorptive surfaces should be within the front part of your home theatre room.

The rear part of your room should contain surfaces that are more reflective to help diffuse better the surround sound within the room from your rear speakers.

It is a widely accepted fact that for the best movie experience in the home theatre, viewing should take place either in total darkness, or under very low ambient light, i.e. either with the lights switched off, or significantly dimmed.

Either too much ambient light in the room or outside natural light coming from windows can create glare on the television screen and washed-out images in the case of projection systems.

In particular, projection systems would ideally require total darkness for the best image quality.

The following tips will go a long way in ensuring that you have the perfect light setting in your home theatre:

Windows that let in bright sunlight should have easily adjustable blinds or curtains made of thick and dark material to reduce the light level in the room while eliminating any reflections off the screen.

You can watch your TV with the lights on - but care should be taken with the positioning of your home theatre lighting with respect to your TV screen to avoid glare.

Special attention should be given to curved screen surfaces. Televisions featuring a flat panel screen such as LCD and plasma are less susceptible to glare.
