Definition

Noun 1. The state or characteristics of a communication channel or environment regarding the presence and effect of unwanted signals or interference that disrupt the intended message. This refers specifically to the quality of a transmission medium, such as a telephone line, radio frequency, or data connection, which is degraded by extraneous energy or disturbances. These disturbances are metaphorically called "noise." 2. The environmental factors relating to sound levels that affect a situation. This can refer to the acoustic properties of a physical space that impact communication, recording, or measurement.

Usage Examples

• Noun:
  • The poor noise conditions on the satellite link made the astronaut's voice difficult to understand.
  • Engineers measured the noise conditions on the power line to diagnose the data transmission errors.
  • The noise conditions in the crowded restaurant made it hard to have a conversation.
  • Before recording the interview, the producer checked the noise conditions in the room.

Advanced Usage

• Technical Specification: In telecommunications and engineering reports, "noise conditions" is often a quantified parameter describing the signal-to-noise ratio (SNR) or bit error rate (BER) of a system.
  • The modem automatically adjusts its transmission speed based on the current line noise conditions.
• Operational Constraint: The term can describe a limiting factor for an activity.
  • Due to high ambient noise conditions, the wildlife survey had to be postponed.

Variants and Related Words

• Noise (n): A sound, especially one that is loud, unpleasant, or disruptive. In electronics, any unwanted electrical or electromagnetic energy.
• Signal-to-noise ratio (n): A technical measure comparing the level of a desired signal to the level of background noise.
• Channel conditions (n): A broader term encompassing all factors affecting a communication channel, including noise, attenuation, and distortion.

Synonyms

• Interference level
• Channel noise
• Acoustic environment (for the physical space meaning)

Related Phrases

• Adverse noise conditions: Particularly poor or disruptive noise levels.
  • The pilot reported adverse noise conditions on the emergency frequency.
• Under noisy conditions: A phrase describing an action taking place despite interference.
  • The system is designed to operate reliably under noisy conditions.

1. the condition of being noisy (as in a communication channel)
