Artificial lighting (Night)0 – 55 CRI = Poor color rendition
Color rendering, expressed as a rating on the Color Rendering Index (CRI), from 0-100, describes how a light source makes the color of an object appear to human eyes and how well subtle variations in color shades are revealed. The higher the CRI rating, the better its color rendering ability.

Acoustic : Pusat Islam UiTM Perak
There are three distinct acoustical requirements for mosques:
• to hear the namaz (prayer) orders of the Imam (prayer leader),
• to understand the sermon of the preacher,
• to listen to or join to the recital of the musical version of the Holy Koran.
Therefore, at the design of a sound system, it is important to use a good simulation data program. Here
a model of the building is made with a computer program. By using a good simulation technician,
different materials, shapes and speakers can be tested in the computer model and with good accuracy to real life, if the model is well designed for its purpose.
The architect is often focused on his problems and targets, which are to design a beautiful mosque. He is not so often aware of the acoustic problems he might cause.
Only people inside Pusat Islam will heard the sound
The sound system should follow the following simple but important rules:
• Loudspeakers are usually unattractive, so they should be heard but not seen.
• Selection of correct type, placement and number of loudspeakers for the purpose.
• Selection of the right type of microphones and other signal sources for the purpose.
• A simple and effective digital control system well programmed to make the use of the
• system as easy as possible.
Sound system rules
People outside Pusat Islam will heard the sound
Due to the often difficult acoustic environments in a mosque, it is important to use loudspeakers with well-defined dispersion characteristics as well as all other technical specifications suitable for the purpose.
These data will give the designer the tools to avoid problematic reflexions and dispersions in the building.
The audience with their clothes are usually the best absorbers available in the mosque.
This also means, the more visitors the better the sound.
By using the correct number of loudspeakers, mounted at the right places, even an acoustically poor mosque can get results much better than expected.
