Each area requires a different equipment configuration to ensure sound coverage and voice clarity. Let’s explore the area-based public address system design solutions with Hoang Bao Khoa, which help deliver clear and accurate information to functional spaces such as elevators, basements, or commercial areas in this article.
Why One-Size-Fits-All Doesn’t Work for PA Systems
One of the most common mistakes in installing PA (public address) systems for buildings, apartments, or shopping malls is using the same type of speaker and the same setup for every area. In reality, each zone – from basements and elevators to commercial spaces – has its own acoustic characteristics and functional requirements.
Designing zone-specific PA audio systems not only improves communication efficiency but also enhances user experience, reduces echo and noise, and optimizes investment costs.

1. Elevator: Small Space, Moderate Volume
Characteristics:
- Enclosed space with strong sound reflection.
- Users stand close to the speaker.
- Frequent announcement playback.
Recommended Equipment:
- Ceiling or surface-mount speakers with small size, 3W–6W power rating.
- High-sensitivity speakers for clear playback even with background music.
- Dedicated zone volume control for easy level adjustments.
2. Basement: Open Space with Noise & Reflections
Characteristics:
- Large open area, low ceiling height.
- High ambient noise from vehicles.
- Humid and dusty environment.
Recommended Equipment:
- Wall-mounted or horn speakers rated 10W–30W, with dust-resistant design.
- Distribute speakers evenly along corridors to avoid sound hotspots.
- Choose products with IP certification (dust/water resistant) and high durability.
3. Commercial Areas: High Aesthetic Demands & Clear Sound
Characteristics:
- High foot traffic and ambient noise levels.
- Visual aesthetics matter – hardware visibility should be minimized.
- Dual purpose: background music and announcements.
Recommended Equipment:
- Full-range ceiling speakers with slim, modern design.
- Smart DSP-based audio management system for volume zoning.
- Centralized controller and zone selector for smooth switching between music and announcements.
Key Considerations When Installing Zone-Based PA Systems
- Design appropriate zones – each should have tailored volume and priority settings.
- Balance emergency announcements and background music to ensure user comfort.
- Prioritize professional-grade audio equipment from reputable brands – easier maintenance and long-term reliability.
