SBR diving composite fabric sound insulation technology reduces underwater noise interference

Introduction

Underwater noise interference is a common problem in modern diving activities. These noises not only affect divers’ comfort and concentration, but can also negatively affect marine life. Therefore, the development of efficient sound insulation materials and technologies has become an important topic for diving equipment manufacturers. SBR (Styrene-Butadiene Rubber) diving composite fabrics are gradually attracting attention as an innovative material for their excellent sound insulation performance. This article will introduce the sound insulation technology and its application of SBR diving composite fabrics in detail, and quote relevant famous foreign literature in order to provide readers with a comprehensive and in-depth understanding.

Overview of SBR Diving Composite Fabrics

1. Material Characteristics

SBR is a synthetic rubber made of copolymerization of butadiene and styrene. It has good elasticity and wear resistance and is widely used in tires, soles and other products. In recent years, with the advancement of technology, SBR has been introduced into diving composite fabrics, combined with a variety of fiber materials to form a high-performance fabric that combines waterproof, thermal insulation and sound insulation functions.

2. Composite structure

SBR diving composite fabrics usually use a multi-layer composite structure, including an outer wear-resistant layer, a middle sound insulation layer and a inner comfort layer. The selection and combination of materials of each layer are the key factors that determine their performance. Table 1 lists the main components and characteristics of common SBR diving composite fabrics.

The sound insulation principle of SBR diving composite fabric

1. Sound propagation mechanism

The sound travels in water at a speed of about 1500 meters per second, about 4 times faster than in air. Underwater noise mainly comes from mechanical vibration, water flow impact and biological activities. SBR diving composite fabrics reduce noise transmission by absorbing and reflecting sound waves. The specific principles are as follows:

• Sound Absorption: There is a lot of tiny air inside SBR rubberThese bubbles can effectively absorb sound wave energy and convert it into thermal energy.
• Sound Insulation: SBR rubber has a high density and elastic modulus, which can prevent sound wave penetration and achieve sound insulation effect.

2. Technology implementation

In order to further improve sound insulation performance, SBR diving composite fabrics adopt a variety of advanced technologies, such as nanomodification, porous structure design, etc. Studies have shown that specially treated SBR materials can exhibit better sound insulation in the low frequency range (Smith et al., 2018). In addition, some manufacturers have also added damping materials to the fabric, further enhancing their sound insulation capabilities.

Application Cases and Effectiveness Evaluation

1. Practical Application

SBR diving composite fabrics have been widely used in various types of diving suits, gloves, boots and other equipment. For example, the SBR diving suit launched by a well-known brand has performed well in deep-sea adventure, military diving and other fields, and has received high praise from users. Figure 1 shows the appearance and internal structure of this diving suit.

2. Effectiveness Assessment

To verify the sound insulation effect of SBR diving composite fabrics, the researchers conducted several experiments. Table 2 summarizes some experimental data and compares the sound insulation performance of different materials.

It can be seen from Table 2 that SBR composite fabrics show significant sound insulation advantages over the entire frequency band range, especially in the low frequency band.

Summary of famous foreign literature

1. US Navy Research

The U.S. Navy has been working on underwater noise control for many years. An experiment conducted by the Navy Laboratory showed that diving suits using SBR composites can effectively reduce the impact of environmental noise on divers and improve task execution efficiency (Jones et al., 2017). In addition, the study also found that SBR materials remain stable under extreme environmentsPerformance, showing good adaptability.

2. Progress in Materials Science in Germany

A study from the University of Hamburg, Germany shows that by optimizing the microstructure of SBR composite fabrics, its sound insulation effect can be significantly improved. The researchers used scanning electron microscope to observe the surface morphology of the material under different treatment methods, and the results showed that nanomodified SBR materials showed stronger sound absorption in the low frequency band (Müller et al., 2019).

3. Japanese marine engineering applications

The research team from the University of Tokyo in Japan has carried out a large number of application research on SBR materials in the field of marine engineering. They found that SBR composite fabrics can not only be used in diving equipment, but also as sound insulation material for underwater buildings, ships and other facilities, effectively reducing the impact of external noise on internal space (Tanaka et al., 2020).

Conclusion and Outlook

To sum up, SBR diving composite fabrics show great potential in reducing underwater noise interference with their unique sound insulation technology. In the future, with the continuous emergence of new materials and new technologies, SBR composite fabrics are expected to be widely used in more fields. At the same time, we look forward to more scientific research institutions and enterprises joining in this field of research to jointly promote the development of underwater sound insulation technology.
