Have you ever been overwhelmed by the constant noise in a crowded store? Or struggled to hear announcements in a busy train station? Noise pollution is a growing problem that can impact the well-being and mental state of both the clients and the staff in different environments.
According to the World Health Organization, environmental noise can cause different illnesses, both short-term and long-term, including, but not limited to stress, sleep disturbance, and cardiovascular diseases.
While public space announcements can become tiresome, innovative technology can offer a solution – directional speakers. This targeted approach not only reduces noise pollution for everyone else but also improves the overall effectiveness of public announcements.
Unlike conventional speakers that blast sound in all directions, directional speakers focus the sound waves into a beam. This means you can target specific areas with sound, reducing noise pollution in unwanted environments.
Optimizing the Soundscape in Banks
One of the environments where noise pollution could be a significant issue is banks. Customer conversations, ringing phones, and announcements can create a cacophony that disrupts both employees and customers. This can lead to errors in transactions, decreased customer satisfaction, and even increased stress levels for the employees.
Directional speakers, also known as ultrasonic speakers, can be a valuable tool for reducing noise pollution in banks. Here’s how:
Quieter teller interactions
Directional speakers installed above teller booths can direct sound towards the customer and teller engaged in a transaction, minimizing disruption for other customers waiting in line.
This allows for more confidential conversations and reduces the need for both the teller and the customer to raise their voices to be heard over background noise.
Targeted announcements
Announcements about bank hours, services, or promotions can be directed towards specific areas of the bank, such as the waiting area, avoiding disruption for customers engaged in consultations with loan officers or wealth managers.
Directional speakers can also be used to discreetly deliver security alerts or instructions to specific zones within the bank, minimizing panic and ensuring clear communication during emergencies.
Noise Pollution Prevention in Transportation Hubs
Transportation hubs, while vital for keeping cities and regions connected, can be significant sources of noise pollution. In such cases, the prevention of noise pollution could be implemented with the help of parametric speakers which would optimize the noise levels in open spaces, like airport terminals.
Audience-specific notifications and multilingual announcements
Train stations and airports can use directional sound to deliver targeted announcements in specific zones. Such sound systems improve the safety and security of the passengers waiting at the train platform. The speakers inform the passengers to stay behind the yellow line, mind the gap, or remember that the doors of the carriage will be closing after short notice.
When it comes to documents, such as passport control or visa checks, directional noise could provide additional information for the arriving passengers.
Directional speakers could inform the people in line about the ID checking procedure and what documents would be needed, whether it’s an ID card, a passport, a specific visa, or immigration papers.
Airport terminal counters could also have designated queues for multiple languages. Markings on the floor or overhead signs can inform which speaker emits information in a particular language (e.g., English, French, or German) so there would be less confusion and the queueing would prove efficient.
Reduced stress levels
The constant thunder of noise in airports, train, and bus stations can contribute to the stress of the passengers and the personnel. Directional speakers create a calmer environment by directing announcements only to those who need them, allowing for a more peaceful travel experience.
Other Possible Noise Pollution Scenarios
Retail settings
Directional speakers can create a calmer, more pleasant shopping experience for both the customers and the employees. Imagine a supermarket where the self-checkout instructions are delivered to the customer personally without the interference of noises made at the other cash registers.
This can greatly improve the purchasing procedure as it enhances concentration and reduces the stress often associated with crowded checkout lines.
Retail stores often echo different announcements about current discounts and other product-related news. Directional speakers, when installed at product shelves, isles, or checkouts can be targeted at particular products to grab the attention of the shoppers. This lowers the overall noise of the store and makes the means of advertising more effective. You can read more about the retail application here.
Industrial facilities
Factories and workshops are known for noise pollution and high-frequency noises. These specialized speakers can be used in control centers to provide accurate information for the operators individually without distracting the other workers.
Restaurants and cafés
Directional speakers could be used to enhance the dining experience of cafés and restaurants. Specific booths could offer personalized musical experiences so that other clients can dine in peace.
The volume of directional speakers could be adjusted according to the number of diners at the table or the occasion – whether it is a romantic or a party setting.
What’s more, they can create personalized listening experiences by localizing different genres of music to individual tables, catering to diverse tastes and special occasions.
Focusonics® for Noise Pollution Control
The placement of directional speakers is crucial for maximizing their effectiveness. They can be integrated into other noise-reduction solutions, e.g., sound-absorbing materials and zoning regulations that can be implemented by using physical barriers to form queues or visual signage on the floor.
Professional expertise can help to achieve the most effective results for your application. The effectiveness of sound localization largely depends on the speaker installation, venue parameters, and other similar criteria. Please, get in touch to discuss your application and get a professional opinion.
The prevention of noise pollution could be achieved with the Focusonics® directional speakers, which offer an innovative solution for focused audio emission.
Focusonics® Model A stands out for its long reach. Effective at distances of 3 to 15 meters, it maintains clear, focused sound even in larger spaces. When it comes to tighter spaces, Model B excels at close quarters. Designed for shorter distances between 1 and 5 meters, it’s ideal for situations where the speaker is mounted overhead.
