Dear Cover,

Does anyone know pokayoke or gages to measures noise ? would you mind share me the picture of the pokayoke/gage ,

Thanks and Best Regards

Try a google search on "sound level meters".

I will warn you that this is a very complex field. You will need a very detailed test spec that documents things like response time, filter setting, distance from source, use of anechoic chamber, etc.

To Poka Yoke, you would have to continuously sample and have an alarm capability.

What are you trying to measure and Poka Yoke?

Does anyone know pokayoke or gages to measures noise? Our assumption at this point is you mean Sound when you say Noise. Correct?

We need more details of what you are trying to do.

Thanks Miner for your suggestion, what i want to measure is level noise.

Dear Marc,

yes, in our site we call it Noise

Thanks Miner for your suggestion, what i want to measure is level noise.
What is the source of the noise that you are trying to measure?

This post takes me back to my days in television. To measure sound (noise) level you need a “Sound Pressure Meter” sometimes advertised as “Sound Pressure Level Meter”.

In addition to measurement sound levels for recording purposes the have the following industrial applications:

- Real time analysis of noise from any source such as machinery or vehicles
- Monitor office or plant noise and store data for later reference and analysis
- Maintain noise level statistics for internal and external audits
- Perform machinery noise monitoring or use for noise reduction programs

What is the source of the noise that you are trying to measure?

Sorry Miner , I couldn;t give you the details but actually our part is a system part, when the part used in system, it will raise sound, but if this sound heard roughly,so it will categorize as failed part, current we use Human sense, but i'm not confidence this method is good to be used.

There are many makers of acoustical/sound measurement instrumentation, and the technology is quite subtle. A good starting point is perhaps the best known maker, Bruel & Kjaer (http://www.bkhome.com/bk_template1.asp?spid=210&ctid=6), often abbreviated as B&K. (I have no relationship to B&K, other than having first used their equipment 40 years ago.)

The B&K website contains a wealth of educational information on sound and acoustics topics, in the Library section and via links.

Here you go, look to your hearts content. And if you want you can research each manufacturer

Noise is measured in decibles (dB) which is a type of pressure measurement

Measurements such as you require will be difficult even with high quality meters (B&K does make good meters). Unless the ambient noise level is quite low, you will require some type of anechoic test chamber.

You will also need to tightly control the location, distance and orientation of the pickup from the device under test. You will also need to specify the filter and scale. There will be differences between dB and dBA (A filter). All of these will affect the result.

An option that I have used was to measure vibration using an accelerometer and correlating that to acoustic noise. Frequencies match, but the amplitudes are in different units and must be correlated by product. It can be difficult to correlate initially, but it makes testing during production easier.
