问题     It’s my honor to be here tonight.
    Our organization is called the Noise Abatement Society that【B1】______ and tries to deal with noise【B2】______ issues. We are currently working to introduce what is called broadband noise technology in different areas.
    Many people asked me what the broadband noise is. It’s very simple actually, if you can imagine 【B3】______ through a wood late at night in the【B4】______ and quiet and you hear a twig【B5】______, you turn automatically towards that twig. And this is exactly what broadband is, you know which direction it’s coming from, you know【B6】______ which side of you it’s coming from. Alarms at the moment are so loud that they actually【B7】______ you. If you’re at a set of traffic【B8】______, you don’t know which direction an ambulance, a police car or a Are engine may be coming from, but with broadband you do.【B9】______. It sounds just like a "shush shush" sound. The alarms you hear at the moment are very rich in tones. But the broadband isn’t. Because it’s not got the tonal content, you know where that sound is coming from.【B10】______
    Broadband noise alarms are being used in a number of places around the country.【B11】______
【B11】
