This paper describes the design of a frequency shifter to suppress acoustic feedback, to be studied by the experimental method. When the frequency shifter is inserted between the microphone and loudspeaker in the public address system, it shifts all frequency components of the microphone signal by a constant amount. By this method two types of distortions due to acoustic feedback in the public address system can be reduced. The sound pressure level in a room can be increased by about 5-8 db on a...

This paper describes the design of a frequency shifter to suppress acoustic feedback, to be studied by the experimental method. When the frequency shifter is inserted between the microphone and loudspeaker in the public address system, it shifts all frequency components of the microphone signal by a constant amount. By this method two types of distortions due to acoustic feedback in the public address system can be reduced. The sound pressure level in a room can be increased by about 5-8 db on a number of auditoriums. For the public address system in free field, which has multiple loudspeakers, it also has the same effect. If the public address system is operated below but too close to the instability condition the frequency shifter can reduce effectively the interference of the regenerative reverberation.

本文叙述抑制声反馈的频移器的设计,并进行了实验研究.当语言扩声系统的传声器和扬声器之间插入频移器时,传声器信号的所有频率分量都偏移一个常量,这种方法可以减少语言扩声系统在有声反馈时产生的两类畸变.对于一般厅堂,扩声声级大约可提高5—8分贝.对于具有分布式扬声器的窒外扩声系统,也有类似的效应.若语言扩声系统临近不稳定状态工作,频移器可以有效地减少再生混响干扰.

Distributing public address system that is made according Hass principium has gained important application,and it may use several delay-time devices Since market can't afford single equipment including multi-delay-time device, we use MCU to develop the equipment

This paper proposes the serial communication converter which provides transparent data transmission services for the hosts and the terminals in public address system. Based on this serial communication converter, terminals in traditional public address systems are able to be used in network public address systems, it provides an effective solution to upgrade public address system from traditional form to network form. The serial communication converter is designed with network single ship processor MC9S12NE64 and embedded TCP/IP stack-OpenTCP, has simple structure, small form, low power consumption, high capability and flexibility.

本文提出一种应用于网络化公共广播系统的串口网桥,为公共广播系统的控制主机和广播终端之间提供了透明数据传输服务,使得能将传统公共广播系统终端应用于网络化公共广播系统中,为实现传统公共广播系统向网络化公共广播系统的升级提供了一种有效的解决方案。该串口网桥的硬件设计基于高集成度的网络单片机MC9S12NE64,配合基于嵌入式TCP/IP协议栈OpenTCP的软件,具有结构简洁,体积小,功耗低,效率高和灵活性强的优点。
