White noise is comprised of all the various sound frequencies and wavelengths that are contained in the spectrum of sound. It makes a sound somewhat like a hum that can be very soothing. White noise is a flat noise spectrum wherein all other sounds that are generated just join it without altering the effect it has on the human ear. This is similar to the principle of a white light spectrum, which does not alter its appearance of white light to the human eye even when extra red light is added to it.
Though complete white noise may produce a sound that is harsh to the ears, white noise sound machines produce a white noise that is more soothing and gentler, somewhat like a fan’s whooshing sound or the sound made by a soothing waterfall. The combination of different frequencies is very soothing and is of great help to those individuals who are easily disturbed by individual sounds including barking dogs and blaring horns.
White noise sound machines are very helpful for people suffering from tinnitus, a condition where there is a constant and annoying ringing in a person’s ears. White noise masks this ringing and changes it to a sound level that is acceptable and allows the person to relax and go to sleep.
White noise sound machines are also very helpful in inducing sleep in babies who suffer from colic. They work by masking the audible environmental stimuli that is believed to be the main cause of colic. The soothing sound that they produce masks harsh external noises and this absence of any audible environmental stimuli helps people get better sleep.
Other than masking the sounds of dog barking, white noise machines also help to quieten and soothe barking dogs as well as other animals that suffer from specific disorders that could be caused by separation or fear.
Getting adequate sleep is paramount to good health. Many people find it difficult to go to sleep or find their sleep being disturbed because of loud external noises. Sleep deprivation is the cause of myriad health problems and is the primary cause of death while driving on the highway. White noise machines are increasingly getting more popular in helping people sleep better by removing all annoying external sounds such as loud music and continual loud talk that disturb daily sleep.
There are several white noise machines of high quality available including the Obus Forme Sound Machine, the Marpac Sleep Mate 980, the Sound Oasis and the Conair Sound Conditioners. Using any one of these can be the solution to your sleep problems.
