In addition, some isolation systems can be excited by acoustic noise.

Air compressors can create problematic acoustic noise, heat, and airflow.

Although not totally silent, electronic drums produce much less acoustic noise than a traditional drum kit.

Oversizing the fans and ductwork can reduce the acoustic noise they produce.

Gradually the noise, both acoustic and mental, died away.

Other dynamic stress inducing factors are shocks, vibrations, and acoustic noise.

Also, electrical interference to telephones or headphones may result in damaging acoustic noise.

Any device with heavy currents passed through coils may produce acoustic noise.

The combination of visual and acoustic noise makes reality appear as "some kind of less authentic, alternate channel".
