Clear in speech. Robust in use. Reliable in daily operation.
Parking garages and underground car parks place special demands on professional audio technology.
Large areas, concrete surfaces, vehicle noise, and different building sections make uniform and intelligible speech transmission difficult. At the same time, announcements and operational information must be able to be broadcast selectively in individual or multiple areas.
A professionally planned sound system ensures that information is as clear and understandable as possible, even under challenging acoustic conditions.
This means:
✓ clear and intelligible operational announcements
✓ uniform sound coverage over large areas
✓ separately controllable audio zones for different parking levels
✓ robust loudspeakers for demanding environmental conditions
✓ flexible expandability for future changes
✓ reliable operation in daily use
Whether it's a smaller underground car park, a public multi-storey car park, a shopping centre car park or a multi-storey large car park: each property has different requirements for its sound system.
WHD develops audio solutions that are planned to match the area, construction, and use – from targeted speech transmission at entrances and exits to zone-based sound reinforcement for multiple parking levels.
And reliably reproduces information clearly and intelligibly
Clearly broadcast operational announcements
Notices, service information, or organizational announcements should be as clear as possible, even with vehicle noise and over long distances.
Targeted sound reinforcement of large areas
Professional planning considers building geometry, loudspeaker positioning, and typical ambient noise to avoid unnecessary volume peaks and poorly covered areas.
Flexibly control parking levels
Entrance and exit areas, individual parking decks, cashier areas or pedestrian zones can be planned as separate audio zones and controlled independently of each other if required.
In a parking garage, audio technology must function reliably without requiring extensive operation.
Announcements must be triggered precisely. Different parking levels should be able to be addressed separately. At the same time, the technical operation should be clearly structured and easy for authorized employees to understand.
This is exactly where a professionally planned sound system provides a solution.
It is...
✓ easy to use – even without prior technical knowledge
✓ accessible only to authorized personnel if desired
✓ separately controllable for individual areas and parking decks
✓ flexibly configurable for various announcement scenarios
✓ designed for professional continuous operation
✓ low-maintenance and long-term expandable
Robust and weatherproof loudspeakers with integrated motion detector and audio memory.
Ideal for modern and stylish parking garages and underground parking facilities where design is important.
For buildings with large, open spaces, high ceilings and open architecture.
For powerful voice announcements in larger, noisy and acoustically challenging areas.
For clear information, announcements and messages with priority over background music.
For reliable distribution, control and amplification of music and speech in single or multiple sound zones.
Whether it's new construction, expansion, renovation or modernization – professional audio technology should be integrated into building and electrical planning early on.
Our team supports project planners, specialist planners and integrators with structured documents such as equipment lists, optimized loudspeaker positioning and optional wiring diagrams.
On request, we can accompany the installation, commissioning and handover together with qualified partners and ensure a smooth project completion.
The focus is on:
✓ zone-based planning
✓ clear system and functional logic for easy operation and uncomplicated use later on
✓ low-maintenance and reliable concepts
The appropriate loudspeaker type depends on the room size, ceiling height, furnishings and desired design. Recessed loudspeakers enable discreet integration, while wall-mounted loudspeakers are particularly suitable for retrofitting. For high ceilings, pendant or spherical loudspeakers can provide even area coverage.
The number cannot be determined solely by the square footage. Key factors include ceiling height, floor plan, surfaces, desired volume and the dispersion pattern of the loudspeakers. Professional planning prevents overly loud areas and acoustic gaps.
Yes. With different sound zones, the various car park decks, outdoor areas, walkways and other areas of the car park can be controlled separately. Depending on the system, volume and audio source can be individually set for each zone.
Yes. Various solutions are available for retrofitting. These include surface-mounted loudspeakers, compact wall-mounted loudspeakers and self-contained loudspeakers.
Yes. Professional audio solutions can combine music and speech. Announcements can be set so that background music is automatically lowered or paused for the duration of the announcement.
For multiple locations, a standardized basic concept is recommended. This defines, among other things, loudspeaker types, audio electronics, operation, zones and basic settings. The concept is then adapted to the size and architecture of the respective location.
We are a medium-sized company with over 40 specialists, 90 years of experience, and more than a thousand projects.
