I must say that the title white noise maker is a little misleading – they don’t produce white noise (white noise is a quite harsh noise) – instead they produce a very soothing sound. This soothing sound in the background will be really good for people who has problems sleeping. The sound can be like rain, wind, and ocean waves. There are a lot of products out there – I am not quite sure if it available in my home town – Thrissur..
