| illbruck Acoustic introduces Noise Canceling Earmuffs  illbruck Acoustic has introduced SONEX NoiseBuster Electronic Noise Canceling, ENC, Earmuffs which provide passive hearing protection with advanced electronic noise cancellation technology. The product provides high-performance ear protection and increased safety for industrial workers, as well as for do-it-yourself users of lawnmowers and power tools, and for motor sports fans. SONEX NoiseBuster ENC Earmuffs deliver noise reduction across the full range of frequencies-up to 20 dB of electronic noise cancellation and passive Noise Reduction Rating of 26 dB.The electronic noise cancellation protection component is the most effective defense against low-frequency noises such as those generated by engines, fans and motors. The passive protection component is the most effective defense against mid- and high-frequency noise such as speech and saws. The electronic noise cancellation technology used in the SONEX NoiseBuster integrates a microphone inside the ear cup that listens to noise coming into the ear. The system analyzes the information electronically and creates an opposite noise wave that cancels the one coming into the ear. The anti-noise wave is transmitted through a speaker, also located in the ear cup. When the two waves meet, the noise is significantly reduced. SONEX NoiseBuster ENC Earmuffs allow critical speech communication to be heard more clearly and users to listen to music or radio communication at lower, less damaging volumes. NoiseBuster can be worn over the head or behind the head. SONEX NoiseBuster ENC Earmuffs include a durable carrying case, battery and audio interface cable. The product features an on/off switch and power indicator, stereo input audio jack and plastic-molded adjustable non-conductive headband. NoiseBuster operates up to 65 hours on a single AA battery and is resistant to water, moisture, contaminants, mechanical shock and vibration. write your comments about the article :: © 2006 Construction News :: home page |
