Translation:This digging tool, the sound is very loud.
Not a common sentence pattern in English so a perfect translation will be hard to come by. Something like "Regarding this excavator, its noise is very loud", or "...the noise it makes is very loud",
Bit tricky even though the meaning of the sentence is perfectly clear.
The noise from this digger is very loud.
The sound of this digger is deafening.
This digger makes a lot of noise.
The sound of this digging tool is very loud, or, this digging tool's sound is very loud.
