What is pink noise vs white noise?

The color of noise usually depends on the distribution of energy over different frequencies or sound speed. Pink noise entails all frequencies that can be heard. But, the energy is not distributed equally. At low frequency, it can become more intense, thus creating a deep sound. It can use both deeper and lower sound waves and become gentle. Examples of pink noise include waves on a beach, steady rain and wind going through trees.

White noise also contains all audible frequencies. Unlike the energy in pink noise, in white noise it is equally distributed across all frequencies. This equal distribution generates a steady humming sound. Some examples of white noise include humming air conditioner, radio static and whirring fan.

Can a white noise machine be too loud?

White noise machines are sufficiently loud to obscure noise pollution. However, they may become too loud to an extent of damaging your hearing. According to the CDC the sounds below 60 dB do not cause any hearing damage. However, anything more beyond that may not be good for you. Some white noise machines can be louder, generating more than 85 dB noise levels. This is  considered too loud for your hearing. This is particularly harmful to young children. 

What is a safe dB noise level?

Noise levels below 60 dB can be considered safe. Between 60-80 you might feel very annoyed with the noise.  Any noise above 85 dB can be harmful to your hearing. 

Do air purifiers produce white noise?

Yes, air purifiers produce white noise. However, you should note that not all of them do. There are specific air purifiers that have the capability to produce white noise. 

Do air purifiers make a lot of noise?

In most cases, noise from air purifiers is ambient, when compared to other noise-producing appliances at home. However, depending on the fan speed and the model of the air purifier, the noise produced can be high. CDC articulates that anything below 60 dB can be considered average noise. This can be compared to a normal conversation or an air conditioner. However, due to the effects of loud noise, we recommend not to have your air purifier beyond 50 dB. This will help you keep your hearing safe. 

Should I sleep with an air purifier on?

You can sleep with your air purifier on. It is okay to leave your air purifier on, since air pollution is a continuous problem. There are no significant health effects to leaving your unit operating the whole night. In fact, the air from the air purifier will aid in easing your breathing as you sleep. However, if you are sensitive to dryness, you need to ensure that the air purifier is not directly blowing into your face. Also, you need to ensure the noise levels generated by the air purifier is less than 50 dB  for adults and you can possibly try to take it to 30 dB if you have infants. Just to be on the safe side.

Is it ok to play white noise all night?

Yes. There is no problem with playing white noise all night. You would not want noise episodes to interrupt your nighttime sleep. You can put on white noise while you sleep. Average white sound noise levels have no effect on your health, even if it is on for the whole night. The average noise levels can be 50 dB, which is equivalent to the sound made by a properly working refrigerator. 

What noise level is safe for babies?

Babies’ ears are more sensitive and can easily be affected by excessive noise. To protect your baby, you need to at least keep the noise levels below 50 db.This can be equated to a quiet conversation or home refrigerator. If you are too cautious you can go as low as 30 db which is equivalent to a whisper or the ticking of a wall clock

The benefits of white noise for babies

  • White noise calms down babies and makes them get the sleep they need.
  • White noise can block other noises to keep the child’s sleep uninterrupted.
