*3.3.1 Sound system components*

What are the sound system and its components? The sound system encompasses three essential elements: the microphone, the loudspeakers, and the controlling devices (**Figure 13**). Microphones are diverse in shape, design, and specifications. Each serves a specific function. The self-switch, the controllable, and the standard normal are all options for the specific situation in the overall interior function and needs. Electrically spoken, the types of microphone differ based on the frequency response, internal circuitry, resistance to the moisture, diaphragm size, weight, and durability. Concerning the loudspeaker, it consists of main parts: the woofer for the low frequencies, twitter for the high frequencies, and the midrange. Finally, the control panel to amplify the sound based on the specific results is required [11].

positions in the interiors.

Why should we use the sound system? The sound behavior in the interior spaces is the result of the interior treatments used. The quality and the properties of these materials share to some extent the overall quality of the sound. Using the sound system is for recording the event (unrepeated or memorial event), for listening to recorded materials (like the cinema), and for the simultaneous translation. Except for these three purposes, the designer does not refer to the sound system since the interior which follows the standard setup will never necessitate such devices.

How to apply the sound system within ideal regulations? The sound system should follow strict regulations to ensure the quality level of the sound projected. Therefore, the strict regulations (**Figure 14**), once applied, will provide the best sound system results. The selection of sound system properties contributes to the overall design of these sound systems in the interior layout. The angles of the sound projections from the loudspeakers determine the numbers of speakers and their

The international meeting and event necessity are the simultaneous translation. In this case, the translation booths should be available by numbers equal to the six

Diffusers are the type of treatments that deploy the sound wave in a way to keep it alive without reflecting it to a specific spot nor to absorb it (**Figure 12**). Diffusers are similar to the reflector properties **but** in altered shapes. They are hard solid materials full of angles and curves to diffuse the sound waves within the interior spaces.

The isolation materials usually are used to prevent the transmission of the sound waves from space to another. Spaces could be enclosed or open, but the essential is to block their flows and thus avoid the noise transmissions. Isolation materials consist of high-density absorbing materials in addition to reflectors in a composition that supports, scientifically and structurally, the sound blockage. However, they are part of the structure of the building layout, yet the acoustical interior may interface to solve specific noise transmission and therefore be part of the design. Building materials are the rescue to solve such situation in the interior

Electrical sound systems for the acoustical interior design are not useful, especially when the interior wall is acoustically designed. It has dedicated purposes when recording constituents play a role in the functional aspects. It is worth to mention that this section is an acoustical engineering field that serves the interior and its inhabitants directly. For the acoustical interior designer, the sound system exposure to three main questionings, the what, the why, and the how of the electri-
