Home Theatre – How To Create? Why not! Even a medium-sized house can have it. Importantly, you know the basic principles. Along with the progress of the times and the rise of the economic level of the community, now many households have a home theatre. Simply put, a home theater can be interpreted as a room where all family members relax to enjoy audiovisual offerings through electronic equipment with quality as in cinemas or music houses.
The success of a home theatre in a private building such as a residential house is not only supported by the availability of sophisticated electronic equipment, but also depends heavily on the design of the space deliberately chosen for the function of the home theatre. Usually, home theatre is more commonly found in upper middle houses.
Nonetheless, it is not closed the possibility for a regular home to have a simple home theatre. This paper provides some basic principles of space design for home theatre purposes. The essence of activities that will be accommodated in a space that serves as a home theater is entertainment and leisure activities (relaxing while enjoying entertainment). Therefore, the design of the space must also be such that a relaxed and comfortable atmosphere can be realized. The comfort in question is very closely related to comfort audio and visually. Visual comfort generally only includes the design on or inside the space itself. While audio comfort must involve outdoor factors.
For example, the music Intentionally raised must provide the atmosphere as desired by the wearer, but should not disturb people outside the room. The sound that emerges from a source will spread in all directions, even under certain conditions able to penetrate the barrier field. When the design of the room is not qualified, the noise that occurs in the home theater will interfere with activities in other spaces. Visual Comfort A home theatre is generally synonymous with the use of a large screen to present images.
Of course, the use of this wide screen will be more suitable when used in a large enough space. Meanwhile, if the available room is not too large, then the use of ordinary television sets can actually still create a home theater atmosphere in a small house. The key to visual comfort is in the selection of screen width or television size that is adjusted to the amount of space available. If the dimensions of the room are not more than 3 m x 3 m, then the use of the big screen will actually make it uncomfortable in watching.
A person remains comfortable and maintains the health of his sense of sight while watching live images.
One is that visibility is at least five to six times the diagonal of the screen. For example, on a 29-inch television (diagonal size of 29 inches), five to six times the diagonal is ± 3.5 m – 4.5 m (1 inch = ± 2.5 cm). If the television is placed in a standard quadrilateral-shaped room, then one side of the room is at least 4.5 m – 5.5 m (Figure 1). The excess of 1 m is left for the laying of conventional televisions (televisions with tubes) and furniture. To reduce glare in the home theatre, the quantity of natural light entering the space should be minimized, so that the image on the screen becomes clearer. The placement of thick curtains on ventilation holes and windows can be an option.
In contrast to visual comfort that only pays attention to the user factor, in designing comfort audio, the user factor of the space and not the space wearer must be considered. So that the user can freely adjust the volume of sound as desired but not Disrupting activities in other spaces, the design of space-forming elements should receive special attention. Interior Design Essence A home theatre does not need to be completed with a bounce finish. This is because the size of the home theatre space is generally much smaller than the cinema building, the number of users is more limited, and the devices used are electronic devices.
More reflecting elements are needed to spread sound evenly distributed to audiences far from the stage on an acoustic presentation system (without the help of electronic devices). In a small room that uses complete electronic equipment, the presence of a reflecting element actually obscures the original sound or sound that emerges from the speaker, because the sound of the bounce arises after a fraction of a second of the original sound. To reduce the transmission of vibrations that arise from low-frequency sounds, it is ideal if the floor of the home theatre room is designed with a raised floor system or double floor.
The double floor design will be quite successful by choosing two different characteristic materials. For example, a combination of a permanent floor with a semi-permanent floor. Permanent flooring, as always, can be tile flooring. Then on it is placed a wooden frame overlaid with wooden planks or multiplexes as a semi-permanent floor.
Using a raised floor arranged with different materials will greatly reduce the transmission of vibrations from the room to the outside of space, because the propagation of sound waves will refract because of the presence of two different materials. To muffle noise such as footsteps that will interfere with the sound of music in the room, the use of thick carpets on wooden boards is highly recommended. In addition to dampening the steps or pounding of the feet, the carpet also serves to eliminate the effect of bounce by the floor.
As well as raised floors, ceilings, as horizontal elements of space will be ideal when designed with a hanging ceiling system (not directly related to the structure of the building). With this design low-frequency sound vibrations can be held to a minimum. To absorb both high and low frequency sounds, the use of acoustic panels that are placed freely in the sky sky of the room will be very helpful.
Special materials such as acoustic tiles or soft board boards that are cut into pieces themselves can be an option. Other materials that can be selected are lanterns from gypsum material. Sound propagation through walls undergoes a slightly different mechanism to propagation through the floor or ceiling. When the floor and ceiling are very potential to transmit vibrations, then the wall has more potential to transmit the sound itself. Sound is able to penetrate very small cracks, because it is ideal if the walls of the home theatre wherever possible are made of massive material (no cracks or defects), heavy (to actually minimize vibration transmission) and thick.
With the choice of this material, air conditioning in the room ideally uses artificial air conditioning (aka AC), so that the possibility of sound breaking through the cracks of natural ventilation holes can be avoided. But with the condition of electricity supply by PLN which is very likely at any time outage, the existence of windows is still needed. Careful window design, by placing sealants on gaps or cracks that occur between the wall with the window sill and between the sills with the filler pan (e.g. glass), will be very helpful. Without a sealant, even if the window is closed, it is very likely that the sound can penetrate into the outdoors. If the sound to be raised by the available audio device is deliberately installed so loudly, then the use of double walls and double windows highly recommended.
Furthermore, to reduce the reflection that may arise because the wall is made of materials with hard surfaces, finishing with absorbing materials such as acoustic tile, soft board or carpet affixed to the wall is also recommended. Materials for walls and ceilings that are able to dampen reflections that are quite cheap in price and widely used in the past are egg containers or fruit containers from processed cardboard paper. This simple container is quite functionally adequate.
This is because the container is made of soft material and forms a basin as Helmholtz resonator that serves to absorb sounds at certain frequencies according to the size of the hole and the volume of the cavity in it. Today, the place of eggs as described may be somewhat difficult to obtain, because today’s egg containers are generally made of hard plastic.
