That noise is part of our life is an indisputable fact. Traffic, music, plays, screams, electrical appliances, children playing are just some of the causes that make us unable to be disconnected, even when we are in our own home.
This excess noise generates a phenomenon known as noise pollution, which WHO points out as one of the four environmental factors that have the most significant impact on people’s health. The European Environment Agency estimates that more than 100 people are exposed to harmful levels of sound in the European Union, which increases the risk of cardiovascular disease, cognitive impairment, sleep disorders, hypertension, and stress. In fact, according to the European Commission, this phenomenon is associated with more than 10,000 cases of premature death each year.
There are many ways to isolate our home so that, within the possibilities, it is possible to maintain absolute tranquility that allows us, at least, to rest at certain times of the day or night. The most conventional is based on the use of certain materials for walls, ceilings, or windows. However, many companies have decided to innovate to offer fast, flexible, and customizable solutions to this problem, thanks to the application of new technological advances.
Here we bring you some examples of the most exciting gadgets so that if the noise at home does not let you rest, you can deal with this uncomfortable situation without the need to carry out works or change doors and windows.
The ‘white noise’ to stop stress
One of the popular methods to escape annoying noises is the use of machines that emit white noise, a type of sound that contains all frequencies.
White noise machines produce a sound that matches the surrounding ambient noise in amplitude, but with the opposite phase, that is, the stage is reversed. When the two sound waves merge, the effects of each one are annulled and create a new sound wave called the antiphase. Noise reduction devices use active noise cancellation (ANC) technology to reduce the invasive effects of background sounds. What these devices do is that they produce a second variety of music that mixes with the original incoming ambient sound stream and cancels the latter’s disruptive effect. This process is known as interference, and the cancellation of the invasive properties of both sound waves is called destructive interference. The antiphase is amplified and projected out of the device as white noise. The resulting sound is much softer, pleasant, and easy for the ear.
These types of gadgets are beneficial for falling asleep since the ear is the only one of the senses that remains active when we sleep. In this way, perceiving pleasant sounds prevents other sounds and louder noises with more disturbing frequencies from distracting or disturbing us.
Some of the alternatives that exist in the market are limited to emitting a white noise that attenuates unwanted noises. Still, others offer a sound therapy experience where you can hear things like waterfalls, waves on the beach, sounds of nature by night, or the fall of the rain, among others.
To sleep, study and work without noise
LectroFan is one of the brands in the sector of white noise machines, launched by Adaptive Sound Technologies, Inc., a Silicon Valley company whose mission is “to adapt the sound to improve life.” Among its products, we find the LectroFan High Fidelity. In addition to white noise, it emits others such as pink noise and brown noise, composed of low and medium frequencies, more severe than white. These three types of noise provide an ideal environment to fall asleep. They are also useful for making studies or workspaces more enjoyable, making it an excellent tool to reduce distractions and increase productivity. Headphones for individual silence
A more individualized option is found in these attractive headphones that can do almost anything: from reducing the volume of noise from neighbors when moving furniture, to silencing the machines of the works on your street.
