DSP350F_Directional Sound Reinforcement System Solution for Playgrounds

Solution Overview

The directional sound reinforcement system for playgrounds is an advanced audio solution designed to provide high-definition sound coverage while minimizing noise interference in the surrounding environment. It not only improves the audio experience in the school playground, but also reflects the importance of environmental protection and complies with relevant policies and standards for noise pollution prevention and control.

Project Requirements

● The system should be able to cover the entire playground, including audience seats and sports areas.

● The system should be able to adapt to different climate conditions and environmental factors, such as temperature, humidity, etc.

● The system should be able to provide clear background music and voice announcements while reducing noise interference to nearby residents, achieving an amplification effect that does not disturb the public.

● The system should be adaptable to various daily needs such as broadcasting or background music, allowing for quick adjustment of the direction and intensity of the sound.

System Architecture-The Directional Broadcasting Configuration of School Playground

● Standard 400-meter running track playground;

● Reasonably arrange the positions of speakers based on the collective environment and acoustic characteristics around the playground;

● Equipped with 1 set of wireless mcirophone system (UHF Wireless Receiver + 2 Handheld Microphones) for speaking;

● Equipped with 6 outdoor directional speakers, designed 3 power amplifiers to promote the work, and also equipped with 1 professional audio mixer and 1 audio processor.

System Configuration Checklist

Advantages

● Directional Sound: The independently developed proprietary high-directivity speaker unit that exhibits a remarkable front-to-back sound pressure level difference exceeding 25dB. It has exceptional directivity, enabling long range sound transmission with precise positioning to avoid disturbing the surrounding environment.

● High sound quality: The speakers' placement is strategically designed based on the Haas Effect, to eliminate unwanted echoes and ensure a superior listening experience characterized by high-quality sound.

● Passive Two-Way Crossover with Enhanced Water Resistance: Crafted from robust and durable PE (Polyethylene) engineering plastic, our speakers feature a passive two-way crossover design and possess an outstanding waterproof rating of IPX6, ensuring reliable operation even in harsh conditions. This level of water resistance allows for continuous performance in a wide range of environments.
