6 FAQs about [Rock drill is noisy]

Why does drilling make a noise?

Gradl et al. (2012) recorded the noise created from drill-rock interactions during drilling by a standard microphone and analyzed the relationship of this noise with the drill’s vibration properties . Sometimes, the analysis of the noise generated by the drilling process can reveal the type (class) of the rock being drilled.

Do drill bits affect the noise level of a drilled rock?

As the hardness and compressive strength of the drilled rock increased, the noise level became more sensitive to the hardness of the drill bits. It was also observed that when drilling with a drill bit of a given hardness, as rotation speed increased, the noise level decreased.

Why does a drill bit make a lot of noise?

Naturally, this process creates some noise at the point where the drill bit comes into contact with the rock . High noise levels are not only detrimental to workers’ wellbeing but may also cause serious safety issues in the workplace. Noise level can also be a good indicator of the performance of the drilling tool .

What is the average noise level of a drilled rock?

Fig 4. View of the drilled rocks. Since the base noise level of the test environment and the drilling machine was measured to be 75–80 dB, before any analysis or comparison, the average of these figures (77.5 dB) was deducted from all measured noise levels.

How to reduce drilling noise?

There are several ways to reduce drilling noise. One way is to use a drill motor with a Quiet Operating mode switch. This allows you to operate the machine without making any noise. Another way is to seal the hole in the wall or ceiling using caulking material. We are going to cover three different method works altogether to do the job silently.

Do concrete drill bits make noise?

Rempel et al. (2019) compared the efficiency, noise, vibration and dust generation of two types of drill bits in the concrete drilling operations . In a study by Masood (2015) the noise level created during drilling of igneous rocks with different properties was measured by a portable device .
