Declared noise levels for electric tools are<br />
below 70 dB(A), and below 80 dB(A) for<br />
pneumatic tools. Angle nutrunners generate<br />
no process noise and, since they are not oper-<br />
ated for prolonged periods during one day,<br />
they do not cause any significant increase in<br />
the noise level at the workplace. Electric tools<br />
have even been criticized for being too silent.<br />
Sometimes the operators do not get sufficient<br />
acoustic feedback when using the tool to judge<br />
the progress of the tightening cycle.<br />

These factors are not an operating problem<br />
for pneumatic or electric tools.<br />
Modern angle nutrunners are increasingly<br />
used in the aerospace industry.<br />
