[Tutorial] An Introduction to Using Markers in NoiseTools – Video

The Markers tool within the NoiseTools software is a powerful feature that allows sections of a measurement to be coded, analysed or removed from calculations. This video introduces the concept of markers and shows how to use the basic functions of the marker system.

Note that this video was made using NoiseTools 1.7.2. The latest version of NoiseTools can be从我们的网站下载.

在本教程中,我们将研究噪声工具中可用的标记功能的简介。我们将从一个示例测量开始,八分钟半。

您可以看到总体基本值,LEQ,LC峰等,以及图表显示噪声水平与时间。蓝线向我们展示了一个第二个LEQ样品,绿线向我们展示了一个第二个峰样品。

[00:00:30]

通过右侧的时间历史记录选项卡访问标记功能。如果徘徊,您会看到两个选项,图形和标记。如果您选择时间历史记录的按钮,我们将获取图形,默认情况下,这将向我们展示一秒钟的LEQ样本。

The options available to us here are to select different data channels, so can have all the information available to us. And we also have available to us the ability to switch on and off certain view settings.

In this example [00:01:00] what we need to be able to show is user markers. So we’ll disable the other two, if they’re switched on, and click …

In this example we’re going to look at how we can use markers to remove particular noise sources from the overall measurement and then to recalculate our total LAEQ. If you remember, our overall LAEQ for this measurement is 93.4dB, quite high.

因此,我们将回到时间历史图。现在,此图上有特定的尖峰和峰值,我们确定其中一些来自发电机[00:01:30],其中一些来自泵。

如果我们可以删除这些,我们希望能够查看这种影响对我们的整体LAEQ有什么影响。因此,首先要做的事情是,我们将在一开始就拖延这三个尖峰,右键单击,我们将放大。它只是让我们更好地了解所看的东西。

Now what we’re going to do is drag over the first spike, right click with our mouse, and select “Mark”. This brings up the “Add Marker” button, and we’re going to call this one, “Generator”.

[00:02:00]我们将选择绿色作为其整体颜色,我们可以在这里写一些笔记。因此,这是一个发电机的启动和停止。如果我们单击“好的”,则特定的噪声被标记为发电机。我们将再次做同样的事情,因此我们会再次标记。在这种情况下,我们将选择现有标记,发电机,然后单击“确定”。

And we’ll do that for the third noise source here. Again right click, “Mark” [00:02:30] and select “Generator”. Click “Okay”. Now we use our mouse wheel just to zoom out a little bit further. And again we can select some particular noise sources, we’ll zoom in and we’ll determine that this one here is a generator starting and stopping.

So generator again. Smaller one next to it, that’s a generator as well, mark that. Select generator. And we’ll carry on doing this for the noise sources in the measurement, working our way through. [00:03:00] The aim is to be able to mark up particular noise sources.

现在,我们确定这是中间的,这是一个特别响亮的人,不是发电机。这是一个泵的启动和停止。因此,我们将标记它,而不是选择“生成器”,我们将创建一个新的标记类型。因此,我们将其名称为“泵”。我们将选择红色的颜色,然后单击“好”。在那里,我们可以看到泵以红色选择。

因此,我们将返回噪音[00:03:30]来源,我们将识别其他泵。因此,强调了一个,放大,标记并选择“生成器”。而且,我们将继续这样做,直到有许多发电机噪声源标记为止。

You can either zoom in or out using your mouse wheel, or you can use the slider bar at the bottom to move across the measurement data. So again, generator. There’s no limit to the number of markers that you can have. Markers can overlap each other. And you can have notes appended to each one.

因此,当[00:04:00]您将鼠标悬停在上面,您会发现它是“发电机”,并且笔记将会出现。

So there we can see, we’ve highlighted a number of generators and we’ve highlighted the pump. If you hover your mouse over one, so we’ll hover over pump, the grey pop out box shows us that the noise level for that particular noise source and at that particular point.

We’re now going to look at looking the marker’s table. So hover and select “Markers” and the table will appear. Now what we see here is a list of all the generator noise sources and the pump noise source that we’ve already selected.

[00:04:30]我们确定的每个噪声源开始时间,结束时间,标签和单个LAEQ。按时间顺序列出。在屏幕的底部,有一个“组合标记”按钮。因此,如果您单击它,现在它显示发电机和整个LAEQ的九个实例。

And at the bottom of the screen we now have a remainder. This is the noise that’s left once all those noise sources have been removed. If we untick some of the markers, [00:05:00] it stays the same.

我们知道,通过消除这些噪音苏rces, our overall LAEQ would go down to 82.9dB. So by removing all those markers, all those marked sections from the noise, this gives you the information to say, “Well, we’d be able to reduce from 93.4dB, if we took all those noise sources out, what would be left?” And the answer is 82.9dB.

Now that we’ve marked up our information, we can right click, and from the pop up that appears [00:05:30] on the screen, we can select, “Export”, “Generate Report”. And the software will create for us a time history measurement report, including all the marked sections.

因此,我们在报告中看到了总体测量数据,仪器类型,校准信息等,以及没有标记的总LAEQ。标记在图表上以颜色显示。

And if you go to page two, we see the tabular format of the data. So here are all the individual markers, the LAEQ for each marker, the total [00:06:00] energy and LAEQ, one minute 13 seconds for the generator, the information for the pump. So we have one instance of the pump, 40 seconds and that was 99.8dB.

在剩下的底部,剩下的82.9dB被从计算中删除了所有这些单独的噪声源。

如果您确定是否提供听力保护,这可能特别有用。如果您进行了一个或两个尤其是在整体[00:06:30]测量中影响的嘈杂部分的测量值,则可以标记这些部分,并确定如果去除这些噪声源,则可以计算出什么噪音。

It would then allow you to determine whether you can use noise control measures, whether you’ve got to provide hearing protection, or by changing work need patterns you can reduce someone’s noise exposure.
