Quiet rating is a term used to describe the acceptable levels of sound in a given environment, ensuring that noise does not interfere with activities such as conversation, concentration, or relaxation. It is often expressed through Noise Criterion (NC) and Noise Rating (NR) standards, but there are no ratings on a scale from 1- 10. The most common noise rating standard used for products like air conditioners is the Decibel rating. The decibel is used in acoustics as the standard unit of sound pressure level, or the loudness of a sound. Sound levels are measured in decibels (dB), with different sounds categorized based on their loudness. For example, a quiet room may have a sound level of around 30 dB, while normal conversation typically ranges from 60 to 70 dB. The LG 18,000 BTU 230V Window Air Conditioner - White, Model # LW1824RD has a dBA Level (High/Mid/Low/Sleep) of 65/63/61...^Ivan.
