Imagine it is summertime and you are checking yourself in a hotel after a long inter-state drive. Bone weary and eyes tired from too much heat and glare from the sun and from the strain of concentrating on driving. You have been imagining your bed in the hotel room and the coolness from the AC after which you can relax and doze off. It has been an hour since you reached your room, but you have not achieved sleep just because of that annoying noise coming from your room’s air conditioning unit. Bad trip isn’t it? For sure the following day you will be nursing a migraine at least, if not an elevated BP.
I am sure you know that decibels (dB) is the unit of measure for the noise emitted by your aircon unit. And that these decibels start at 0 dB for the smallest noise you can hear and increases in multiples of 10 dB as the noise intensifies. Further, to appreciate the idea of measuring noise in this case the noise from the aircon unit, let us take the example of normal breathing which produces around 10 dB on the average. Talking is about 40 dB to 60 dB. An example of a loud noise such gunshot can reach up to an approximate of 140 dB. While noise coming from the aircon unit on the average is between 37 dB to 82 dB, for a disparity of 45 dB in between.
It is said that as of now noise from anaircon unit is still unavoidable but can be reduced to so much low dB for an absolute quietest aircon experience. As for the case of your hotel room aircon unit, that fact that it was at an annoying level only tells us that such aircon unit must be old and/or defective and already in need of replacement.
NIHL or Noise-Induced Hearing Loss can both be temporary or permanent and can occur in both ears or one ear only. It is an unfortunate condition which we can definitely prevent by managing the noise levels we expose ourselves on a daily basis. Findings show that exposure to noise of 75 dB even over a long period of time are unlikely to cause Noise-induced hearing loss. However, long and repeated exposure to noise level of 85 dB or more can cause noise-induced hearing loss. As to the question of the NIHL condition being temporary or permanent would depend on how soon such condition is properly corrected with necessary medical care.
Thus, aircon units emitting noise of up to82 dB should be retired already since there is only a difference of about 3 dB between such noise level and the 85 dB cut off for cause of noise-induced hearing loss. To think that you spend at least an average of 8hours sleeping in an aircon room on a daily basis. This falls under the category of “long andrepeated exposure” to aircon noise.
Thanks God Almighty the air conditioners available in the market today are becoming more technologically advanced. Hurry and make sure you install one in your home today.
Also, upgrading your air conditioner unitto a quieter model is the more neighborly and politer thing to do to avoid causing discomfort to others nearby.
