Introducing Octave Band Filters for the doseBadge5噪声剂量计
我们很高兴地宣布，卷轴dosebadge5噪声剂量计now includes 1:1 Octave Band Filters as standard*, adding to the already comprehensive set of measurement data that the unique doseBadge5can provide.
dosebadge5is already the best specified dosimeter available with multiple measurement channels, comprehensive data logging, Bluetooth®无线通信以及原始无线噪声剂量计的前几代的所有独特功能。
The addition of octave band filters advances the doseBadge5进一步提供真正独特的产品，该产品提供了对职业噪声暴露的测量，分析和控制所需的所有信息。
添加到dosebadge5?
已添加到Dosebadge的关键功能5in the update is the ability to measure and store the frequency content of the noise in 1:1 octave bands from 63Hz to 8kHz throughout a measurement, storing both the overall levels in each band alongside detailed time history, or noise profile, data.
传统上，噪声剂量表只能以诸如laeq之类的整体价值来弥补噪声暴露。随着仪器为满足新法规和标准的开发，添加了诸如LCPEAK和LCEQ之类的功能，以及数据记录，为用户提供了详细的视图，了解噪声水平在整个测量过程中的变化。
The new doseBadge5added the ability to measure up to 4 independent channels of data (or integrators) alongside 2 Peak channels as well as the measurement of maximum levels across all channels.
此dosebadge的新更新5允许仪器不仅可以根据整体级别提供噪声暴露，而且还可以在噪声的频率内容方面提供噪声。除了总体噪声曝光数据外，每个八度频段中从63Hz到8kHz的频率未加权的LEQ，但除此之外，Dosebadge5also gives the frequency information in detail, typically sampled at a rate of 1 second.
By providing not only the overall data but the detailed 1 second information as well, the doseBadge5can be used with the NoiseTools software to determine the most appropriate hearing protection for both the entire measurement and for specific noise sources.
In the example below, a measurement made with the doseBadge5分成几部分,这些标记为different noise sources:
Different noise sources marked in NoiseTools
Individual noise sources within a long measurement can be identified and marked using the Markers tools in the NoiseTools software. For example, the person being measured may have been using a range of different power tools throughout the day, each of which will have a different frequency signature. It may be that the hearing protection that is suitable for one tool may not provide sufficient protection, or may even over protect, when used with a different tool.
By identifying and marking these different noise sources, the NoiseTools software can run the hearing selection calculation against all marked sections, allowing a suitable product to be selected for all highlighted areas.

The new filters meet the requirements of the latest standards for filters on a noise measurement instrument, IEC 61260-1:2014 Class 2 and ANSI S1.11-2014 Class 2, and cover the range of 70dB to 140dB.
The Octave Bands can be disabled as required through the NoiseTools software, allowing the battery life to be maximised or where long measurements are needed.
*作为介绍性报价（直到2018年1月1日），这项新功能是标准的5噪声剂量计s at no additional cost. Existing users of the doseBadge5can benefit from this new feature by updating their instruments when they are returned to Cirrus for calibration.
A new version of the NoiseTools software will be released to support these new features and this will add further capabilities to the software.
