EDUCATIONAL CENTERS
A school's public address system is a vital tool for ensuring safety and effective communication between management, teaching staff, students and visitors. A well-designed system can be used to make announcements, play music, provide information in case of emergency and create a safe and positive environment in the school. Messages can be directed to specific areas of the school, avoiding disruptions to classes and improving student engagement.
What do we ask of the public address system?
- Sound coverage: All areas of the school must be covered, including classrooms, corridors, playgrounds, sports areas and common areas.
- Sound intelligibility: Sound must be clear and intelligible in all areas, even in environments with high ambient noise.
- Adjustable volume: It must be possible to adjust the volume for different situations, such as general announcements, background music or emergency messages.
- Flexibility: The system must be flexible and adaptable to the different needs of the school. It must allow the connection of different sound sources, such as microphones, CD or MP3 players, computers and alarm systems.
- Ease of use: Especially for school staff, without the need for specialized technical knowledge.
- Reliability: It must work smoothly at all times, with total reliability.
- Safety: All applicable safety regulations must be met.
- Aesthetics: It must integrate harmoniously into the aesthetics of the school.
- Maintenance: The system must be easy to maintain and repair.
Some specific requirements
- Classrooms: Classrooms should have individual speakers that allow the volume to be adjusted to the specific needs of each class.
- Hallways and common areas: Hallways and common areas should have evenly distributed speakers to ensure uniform sound coverage.
- Playgrounds and sports areas: Playgrounds and sports areas should have weatherproof speakers that can play sound at high volume.
- Emergency areas: Emergency areas should have emergency-powered speakers that can operate even in the event of a power outage.
Example
School, college or educational center of approximately 1000 m2 with live notifications (location/information) and pre-recorded with time control and possibility of remote activation (class change/alarm)
POWER CALCULATION
Approximate surface area of 1,500 m2
- Lobby and corridors (450 m2): 12 x ceiling speakers connected to 3 W
- Classrooms (100 m2 each): 6 x sound projectors connected to 20 W
- Courtyard (450 m2): 2 x horn speakers connected to 15 W
TOTAL: 12 x 3 + 6 x 20 + 2 x 15 = 186 W
