Standard Hydrophone BRC-50A

Product Overview

A hydrophone is a high-performance underwater microphone designed to capture even the faintest sound signals in water. With outstanding sensitivity and a broad frequency response range, hydrophones play a crucial role in marine research, acoustic monitoring, fish monitoring, and various other applications.

Core Application Areas

• Marine Research: Used for capturing and analyzing natural acoustic phenomena in the ocean, helping scientists study ecosystems and environmental changes in aquatic environments.
• Underwater Acoustic Monitoring: Monitors and records noise pollution in underwater environments, including industrial noise, ship sounds, and natural sound sources, contributing to environmental protection and regulation.
• Underwater Detection: Utilizes hydrophones for sonar-based detection and location of underwater objects, widely applied in diving exploration, marine engineering, and military fields.
• Fish Monitoring: Captures sounds emitted by fish and other aquatic organisms to conduct ecological monitoring and population studies.

Product Features

• Exceptional Sensitivity: Capable of detecting even the faintest underwater sounds, ideal for high-precision acoustic monitoring.
• Wide Frequency Response Range: Covers low to high-frequency bands, making it suitable for various application scenarios.
• Extreme Environment Durability: Pressure-resistant, corrosion-resistant, and waterproof, designed for deep-water and harsh underwater conditions.
• Low-Noise Design: Ensures clear capture of target sounds even in complex background noise environments.
• Long-Term Stable Operation: Designed for continuous monitoring tasks, providing reliable data over extended periods.

Application Examples

• Marine Ecosystem Monitoring: Real-time monitoring of oceanic sounds to understand the behavior of marine life and environmental changes.
• Underwater Detection & Rescue: Used in conjunction with underwater robots, hydrophones relay detection data for underwater target localization and emergency rescue operations.

• Acoustic Pollution Monitoring: Hydrophones provide scientific data to monitor underwater noise pollution caused by urbanization and industrialization, supporting environmental protection efforts.
