Losonnante, a company transforming the way visitors connect with sound in public and cultural spaces, works with public space managers and event organisers to overcome a common challenge: delivering clear sound outdoors.

Drawing on this experience, the company has shared its key considerations and looks at some of the most effective options for outdoor sound systems.


"Regulations, technical constraints and requirements to avoid noise pollution make the choice of equipment far from straightforward," says a spokesperson from Losonnante.

"From outdoor PA systems for concerts to discreet directional sound systems in heritage sites, even the best outdoor speakers come with challenges."

Noise control regulations

Before specifying a sound system for an outdoor space, it is vital to understand the relevant regulations. Non-compliance can result in fines, restrictions, or even shutdowns.

In the UK, for example, national legislation and local authority by-laws control noise in public spaces to protect the health and well-being of nearby residents.

Environmental regulations set limits on the level of amplified sound in public spaces. For special events like outdoor concerts or festivals, the allowed levels vary by location, time of day, and local council guidance. Organisers must ensure volumes are safe and minimise disruption.

Additionally, events that use a public address system may need a Temporary Event Notice (TEN) or other event licence from the local council. In some events, such as those held near residential areas, a noise impact assessment may also be required.

Selecting a sound system

When selecting a sound system for their project, organisers must navigate these regulatory requirements while also considering the audience, setting, and overarching objectives.

Popular sound system choices range from loudspeakers to wireless headphones, with each offering its own benefits and drawbacks.

Loudspeakers, for example, offer wide, powerful coverage suitable for large-scale events and open spaces such as festivals and sports fixtures. However, they are sensitive to inclement weather and pose a risk of noise pollution if not strictly managed.

In contrast, directional sound systems reduce noise pollution by providing higher-quality sound to targeted areas. Best suited to smaller, more sensitive venues, this approach brings higher costs and more complex installations.

Other technologies, such as wireless headphones, eliminate noise pollution entirely. Headphones provide personalised, immersive listening for each visitor, but can be operationally and technologically demanding as the equipment needs to be robust, comfortable, and well-maintained.

Another common choice is the 100V line system, which connects multiple speakers over long distances for wide sound coverage across large areas. However, this requires specific cabling and compatible amplifiers, and can result in lower sound quality.

Silent sound systems

Losonnante's bone-conduction audio terminals offer an alternative. These silent sound systems overcome the difficulties of outdoor audio by transmitting sound directly to the listener. When they rest their elbows on the device and cover their ears, sound vibrations travel through the bones to the inner ear.

The system provides an immersive listening experience that is suitable for any public space. It is unaffected by sound loss through the air, weather conditions, or ambient noise, creates no noise pollution, and is fully compliant with the UK's PA system regulations.

It has been deployed for events such as Paris Zoological Park's summer sensory zone, the Saint-Étienne International Design Biennial, and BMW’s electric car launch, to create engaging, immersive outdoor sound events.

"Whether you’re showcasing heritage sites, creating immersive sound experiences or staging cultural events, Losonnante offers a solution tailored to the needs of public space managers and event organisers," says the company.

"For UK organisers, the best sound system for outdoor events is one that complies with event noise regulations, avoids complaints and still delivers clarity."

Last month, Losonnante shared how sound, as one of the most evocative carriers of emotion, helps bring exhibition designs to life.
