Beijing Primary School

Home ProductEducation

Background

Beijing Primary School is a model public boarding primary school. However, because the campus playground is close to residential buildings, every time the school broadcasts announcements, the loudspeaker noise spreads outside the campus. This often disturbs nearby residents, impacting their daily lives and creating complaints about excessive noise pollution.

Requirements

Clear Coverage

Ensure clear and intelligible announcements in the main playground area.

Noise Reduction

Prevent sound from spreading to nearby residential buildings.

Compliance

Keep noise levels in residential areas below 55 dB to meet local standards.

Better Communication

Support effective daily communication for teachers and students without causing disturbance.

Community Harmony

Maintain a balance between school broadcasting needs and neighborhood comfort.

Solution

SPON proposed the use of directional speakers specially designed for focused audio projection. Unlike traditional loudspeakers that spread sound in all directions, directional speakers use advanced acoustic technology to concentrate sound energy only within the intended area.

By deploying SPON directional speakers in the playground:

Precise Sound Coverage

Delivers clear announcements to the entire playground without excessive volume.
Noise Control

Effectively keeps residential area sound levels below 55 dB, preventing complaints.
Directional Technology

Uses advanced acoustic beamforming to focus sound waves, reducing unwanted reflections and reverberation.
Community-Friendly Solution

Balances school communication needs with neighborhood comfort.
Energy Efficiency

Fewer speakers are needed compared to traditional systems, reducing installation and maintenance costs.
