英国 Pulsar环境噪声监测

 Environmental noise is a major issue in most countries, especially in areas of high population, and the sources of noise and their adverse effects on our well-being are varied.环境噪声是一个重大的问题在大多数国家，特别是在高人口地区，噪声的来源和对我们的福祉的不利影响是多方面的。 红外线测温仪| 温湿度仪| 红外线温度计| 露点仪| 亮度计| 温度记录仪| 温湿度记录仪| 光功率计| 粒子计数器| 粉尘计|

In terms of assessing the impact of these issues, we need to be able to make suitable noise measurements, or in some cases monitor the noise levels for longer periods.在评估这些问题的影响而言，我们需要能够作出适当的噪声测量，或在某些情况下监视长时间的噪音水平。

Industrial noise, for example, is a much more exact science, as you are interested in assessing specific noise levels and relating these to legislative or action levels.工业噪声，例如，是一种更为精确的科学，因为你是在评估特定的噪音水平与这些有关的立法或行动水平兴趣。

Environmental noise is very different because the level of annoyance or nuisance can be very subjective and will elicit diverse reactions from different people.环境噪声是非常不同的，因为烦恼或滋扰的水平可以是很主观，并会引起不同的人不同的反应。

Examples of typical noise sources: 噪声源的典型例子：

• Industrial Sites工业用地
• Construction Work党建工作
• Road Traffic道路交通
• Animals (Dogs barking)动物（狗叫声）
• Aircraft noise飞机噪音
• Entertainment venues娱乐场所

Environmental noise can also have different characteristics: 环境噪声也可以有不同的特点：  

• Continuous连续
  • Extraction Fans, compressors etc提取风机，压缩机等
  • Road traffic道路交通
  • Industrial Processes工业过程

• Intermittent断断续续的

  • Transport运输
  • Construction建设
  • Animals动物
  • Industrial Processes工业过程
• Broadband (Noise that has a fairly even tone content and less annoying)宽带（噪音，有一个相当甚至更讨人喜欢的内容和语气）

• Tonal Noise (Noise that has dominant tone(s) that can be very annoying)音调噪声（噪声有主基调（县），可以非常恼人）

  • 'Whining' machinery '呜呜的机械设备
  • Low frequency noise that causes vibration within surrounding buildings etc.低频噪音导致周围建筑物内等振动
  • Wind turbines风力涡轮机

Types of noise measurements噪声测量的类型

 1. 1。 Basic noise level checks or 'spot checks' 基本噪声级的检查或'抽查'

Often you need to take quick decisions and understand if there are likely to be any noise issues.通常你需要采取迅速做出决定并了解是否有可能被任何噪音问题。 By using a simple sound level meter such as the Model 14 you have a cost effective, compact and 'easy to use' instrument that can be easily transported, allowing you to make a quick judgement regarding noise levels.通过使用诸如简单的模型14声级计你有一个符合成本效益，结构紧凑，'方便使用'的工具，可以很容易地运输，让你迅速做出判断有关噪音水平。 This is particularly useful where a more expensive instrument would be cumbersome and more prone to the risk of damage or misuse.这是特别有用的地方更昂贵的仪器将十分麻烦，更容易出现损坏或误用的风险。

The Model 14 is supplied with a wind-shield as standard to protect the microphone capsule and has two selectable ranges to allow you to quickly gauge both environmental and industrial level noises.该模型是配备有14个风标准，以保障麦克风胶囊盾，有两个可选范围，让您快速测量环境和工业水平的噪音。 The instrument is compliant with IEC 61672 and can be supplied with an acoustic calibrator if you wish to verify your measurements – as really should be done.该仪器符合IEC 61672标准，可与声校准器提供的，如果你想验证你的测量 - 作为真正应该做的骏凯电子批发英国 Pulsar 噪音计。

2. 2。 Single but more detailed measurements 但更详细的测量单

Environmental requirements and legislation vary based on your country, locality and specific circumstances.环境要求和立法根据您的不同国家，地区和具体情况。

Often a hand held integrating sound level meter such as the Model 30 would be mounted on a tripod at a boundary position and, for example, a 15 minute measurement made.通常，一个手持集成示范等30人是在边界上的三脚架安装位置和声级计，例如，一个15分钟的测量制成。 Often it is necessary to make a series of similar 'fixed duration' measurements and store these into the instruments memory (for subsequent analysis) for which the Model 30 or Model 33 are ideal.通常，有必要做一个类似'固定期限'和一系列测量仪器记忆存储到这些（供日后分析）该模型30或33个型号的理想选择。 The usual stored information may consist of the 'A' Weighted Leq, LN values, SPL values and perhaps 1:3 Octave Band information for tonal analysis.通常存储的信息可能包括的'a'加权的Leq，LN的值，声压值，也许1:3倍频为音调分析信息。

3. 3。 Longer term monitoring 较长期的监测

 Sometimes we need to monitor noise levels on an ongoing level and make longer measurements sub-divided by shorter measurement durations such as 5 minutes, 15 minutes or 1 hour.有时候，我们需要不断监测水平的噪音水平，使子长测量由测量持续时间较短的划分，如5分钟，15分钟或1小时。 This allows us to look at, for example, a 24 hour period and find the average, background or maximum noise levels for every 15 minute period throughout the day.这使得我们可以看看，骏凯电子批发英国 Pulsar 噪音计例如，一个24小时内找到每15分钟的时间内，全天平均，背景或最高噪音水平。 This gives us a much clearer picture of noise patterns and how they can be controlled to minimise their impact on the wider community.这给了我们一个更清晰的图像噪音模式，以及他们如何可以控制，尽量减少其对更广泛的社会影响。 Often, lower noise limits will be set during the late evening and night due to the extra impact of any noise.通常，低噪音限制将被设置在傍晚和夜间因任何额外的噪音影响。

Tonal Analysis音调分析

There are many engineering solutions available to reduce noise levels and by performing a 1:3 Octave Band Analysis before and after this work you can determine and report the effectiveness of such improvements.有很多的工程解决方案通过执行这项工作之前和之后，骏凯电子批发英国 Pulsar 噪音计你可以决定并报告这些改进的成效1:3倍频可供分析，以减少噪音水平及。
