If you need something as a way for you to improve your concentration, here is an alternative that may deserve a try.
Noisli is a really cool tool that you can use to help you have more concentration and be able to cancel the outside noises and even avoid the silence that you are and simulate as if you are in nature, just by hearing a lovely chirping bird in your ears.

You can either choose those sounds yourself, or you can have a click of a button assist you with a predefined set of combinations that are intended to help you.

It gives you three different types of sound combinations that you can choose from, depending on the intention that you have at that particular moment. If you want to help yourself concentrate better, then you can simply use the combination of sounds labeled as Productivity, which actually offers a variety of sounds that you can listen to. Besides Productivity, it also gives you the Relax and Random sets that you can choose.

If you start to use it, you may notice that each time you choose Productivity or any other form from the ones that are given, you may get another combination, which makes it interesting so that you are actually having a richer variety to choose from.

If you want to have a particular sound that is already included in these combinations to have a lower or a larger impact in the sound combination, then you can simply tweak those yourself.

If you want to have that type of customized sound, which is not actually offered with any of the given alternatives, then you can simply do that by using your own desires, and have the opportunity to actually change the impact that specific sounds may have and actually increase the noise for some of the types that you may prefer.

You can even set a timer and hear that set of sounds for a time period that you choose, which is related to the Pomodoro technique. You can also choose your favorite combinations of sounds and have them ready to use each time you want so that you do not want to start from the beginning the next time you want to play that exact set of sounds.

It also has a Chrome extension that you can use and also register and use it based on your customized needs. This way, you do not have to keep an extra tab open when you are actually using it.

Moreover, Noisli has also a text editor embedded that you can use to write down something, which is intended to be a simply put user layout so that it is easier for you to write without distractions.

If these resonate with you, then I recommend you to give Noisli a try and see how it goes.
