Overview

You may notice that the noise reading (in decibels or dB) of your air conditioner appears higher than the sound level listed in its specifications.
This is normal and usually caused by the difference between controlled test conditions and real-world operation.

Why the Measured dB Reading Can Be Higher

The sound rating published for your air conditioner is measured in a quiet, open laboratory environment under specific conditions—usually at the lowest fan speed.
When the same unit operates in your home or office, several factors can affect how loud it sounds:

  • Operating Conditions – When the system works harder (for example, on a very hot or cold day), it runs at higher fan speeds, which naturally makes it a little louder.

  • Room Acoustics – Hard surfaces such as walls, tiles, and ceilings can reflect sound, making it seem louder than in a test room.

  • Distance from the Unit – Noise ratings are measured from a standard distance (often 1 metre). Standing or measuring closer to the unit will show a higher reading.

  • Background Noise – Other nearby sounds can interfere with measurements and influence the results.

Understanding Sound Power and Sound Pressure

It’s helpful to know the difference between the two ways sound can be measured:

  • Sound Power (Lw):
    This is the total amount of sound energy the air conditioner produces. It’s measured in a controlled test environment and does not change from one location to another.

  • Sound Pressure (Lp):
    This is what you actually hear at a certain point, and it depends on your room layout, materials, and how close you are to the unit.

In simple terms, sound power is the unit’s potential to make noise, while sound pressure is how that noise is experienced in your space.

What This Means for You

A slightly higher dB reading in your home or workplace does not indicate a fault with the air conditioner.
It simply reflects the influence of the environment and operating conditions around the unit.
If noise ever seems unusually loud or changes suddenly, it’s best to contact our service team for further assessment.

Summary

  • The published dB rating is measured under ideal, laboratory conditions.

  • Real-world readings vary depending on how and where the unit is installed.

  • This variation is completely normal and not a sign of a problem.
