Meeting rooms and boardrooms offer convention attendees the same capabilities as their conference rooms at the home office. These speakers can be mounted in a variety of ceilings, with mounting options available for a wide range of materials. Such installations may be logistically problematic for a number of reasons, and may not be the most desirable, but they must occasionally be used.
Audiences ideally want to localize the sound source to the stage. As humans, we tend to localize the source to the first arrival. Adding delay time to the speakers beyond this proximity location makes for a more natural listening experience. That said, even in other installed speaker applications such as public address systems , it still might not be possible to mount the speaker in the ideal location to get suitable coverage without echo.
In these cases, speakers with beam steering capabilities, like the JBL Intellivox and CBT Series , provide a good alternative, as they can adjust the directionality of the sound either through software control Intellivox or with physically adjusting the speaker itself CBT Series. In addition to looking at where the speakers are installed in a space, you also need to look at how many different spaces you have that need speakers.
For example, different spaces might have different ambient noise levels, depending on the size of the space, building materials, number of people, etc. Alternatively, certain areas, such as the lobby of a restaurant, might have seating announcements while other areas, like the dining areas, might only want background music. In either case, zoning allows the system designer to send different content to each area. When speakers are going to be installed in public areas, particularly outdoors, there are some additional concerns that should be addressed as well.
You should never install indoor-only equipment in an outdoor environment. Speakers that installed outdoors should be outdoor rated. You also need to address life safety considerations. Organizations, such as shopping centers, hotels, casinos, theme parks, airports, train stations and other buildings that open their grounds to others, especially the general public, are typically held to a higher government standard.
These places face a large number of government regulations to ensure sufficient care has been taken regarding fire detection, public address systems and more. Speech communicated over the speakers need to be highly intelligible if they are used to distribute life safety messages in noisy environments, a capability that is measured using a number called the speech transmission index STI. Achieving a specific STI number for voice evacuation systems is a requirement than differs regionally.
