* safe, non-chemical insect eradication treatment.

### sound | noise:

Boom
* Linking the shoulder, elbow and wrist joints are the upper and lower arm booms.
* always slow down, though, and time always moves forward.
* are barriers that extend about three feet below the water surface
  - happening
  - mechanical devices
  - part of sailing vessels

  - used to contain oil in pond

Clash
* are bands
  - conflict
* is noise

Crackle
* are chinas
  - comparable to the surface noise on old records
  - unaffected by coughing
* is noise
* usually occur during inspiration.

Crunch
* are a great way to increase stomach strength
  - shortages
  - shorter lifts that focus purely on tightening the stomach muscles to the lower back
  - situations
* help tone abdominals.

Electrical noise
* appears in the output voltage causing small instantaneous errors in the output.
* can also be a byproduct of corrosion.
* is distortion of the voltage wave form, whether at a high or low level.
* is generated by any device that uses or generates voltages that vary over time
  - the alternator, fan motors, windshield wipers, brake lights, etc

Environmental noise
* affects health and well-being physically, mentally and socially.

  - small variations in the voltage of the power line
  - term used to describe the corruption of data as it travels between two modems
* problem that can occur in less modernized countries.

Phase noise
* consists of both high and low frequency components.
* is caused by a random, time-varying carrier frequency and phase drift.

Rumble
* are produced during mild arousal and some appear to be infrasonic.
* is noise
