Customized Loudspeakers: Meeting the Demands of the Mass Transit Industry

Loudspeakers in trains, buses, and other mass transit systems are essential for clear audio to keep riders informed and convey important messages during emergencies. Creating these systems demands careful material selection and rigorous testing to ensure durability and performance.

First Stop: The Right Materials

Proper ingress protection (IP rating) is crucial for an industrial loudspeaker, requiring waterproof materials and designs that shield the loudspeaker’s sensitive components. For instance, a MISCO loudspeaker from Eurocoin, designed for bus exteriors, uses a single-piece polypropylene cone and a neoprene gasket with a cutout to prevent water buildup.

An aluminium or steel grille is common for covering a transit speaker to protect it from vandalism. This can be taken a step further by adding a security screen between the cone and the grille. This screen can prevent sharp objects from being poked through the grille and damaging the cone.

Next Stop: Intelligibility

Durability should not compromise sound quality. Transit loudspeakers must ensure voice intelligibility, performing well within the human voice frequency range (200Hz to 7kHz). High sensitivity (92-93 dB) is also essential for overcoming background noise and ensuring energy efficiency. MISCO from Eurocoin uses Klippel technology to test and verify loudspeaker performance in real-world environments, providing detailed loudspeaker specifications and models. This equipment enables the creation of polar and balloon plots, along with detailed acoustical modeling inside a railway station or bus.
