If you are someone who needs “white noise” to work, relax, or block out the chatter of an office or coffee shop, Noisli may be the website for you. On this site, users can select to listen to a variety of noises, including rain, leaves, and railroad tracks. Alternatively, users can search for a previously composed collection of sounds, designed for either productivity or relaxing. By creating a free account, users can also save their favorite white noise medleys for future use. This will be added to Entrepreneurial Resources Subject Tracer™.
