We have already discussed the best white noise machine available in the UK, but what about the best sound therapy machine? First we need to clarify the difference between a white noise machine and a sound therapy machine. A white noise machine specialises in a select range of sounds and frequencies, specifically white, pink and brown noise. They can also include sounds replicating traditional fans as they produce a white noise and oscillating noise many find helpful. A sound therapy machine on the other hand usually doesn't specialise in a specific range of sound and instead opts for broad spectrum often focusing around nature sounds. These may include things like ocean, meadow, fireplace and rainfall but can also include lesser known sounds such as a heartbeat, train ride, crowds talking and meditation sounds. It's worth noting, sometimes they can be called sleep therapy machines.

Now you know what a sound therapy machine is, I can explain what makes a great one!

1) Non-looping recordings and sounds - You can’t simply record a nature sound and set it on an infinite loop. Why? Well, although you won’t notice it initially, you will eventually clock on to where the loop starts and ends, or you may hear a particular noise and then realise it occurs every 60 seconds. Imagine a bird call in a meadow, at first it would sound absolutely fine but after you hear the same call several times it will become incredibly distracting. It’s not something you want to focus on when you are trying to clear your mind and get some rest. Without giving away the secret sauce, our range of sleep therapy machines have microprocessors that process a number of tracks that dynamically generate a sound. When these tracks are combined, it creates a unique, non-looping, dynamically generated sound profile that we call a soundstory. It’s clever stuff which has taken years of incremental development to get right.

2) Adjustable sound profiles - Our range of sound machines have a feature called <em>Richness</em>, which is sometimes called the <em>Selection</em> button on the device. This is a rather unique, yet important feature which allows the user to customise their sound profile just how they like it. Before you think this sounds too complicated, it isn't. You simply press the Richness or Selection button and a light will appear to let you know what Richness setting you are on. The higher the Richness setting, the more sounds are added to the sound profile. All of these settings can be found in the manual of the device, but for reference <a href="https://www.soundofsleep.co.uk/wp-content/uploads/2019/04/sound-sleep-se-richness-selection.jpg" target="_blank" rel="noopener"><span style="text-decoration: underline; color: #58c8f4;">click here</span></a>.

Here's an of an example of Richness on an Ocean sound profile:
<ol>
 	<li>Richness 1 (no lights) - Waves and lapping water. The waves sounds more distant and consistent.</li>
 	<li>Richness 2 (right light) - Waves, lapping water and gurgling water. The waves sound move in and out and occasionally splash on a rock close by.</li>
 	<li>Richness 3 (left light) - As above but also with gulls, seals and buoy bells. These sounds blend in perfectly and are not so frequent to be distracting.</li>
 	<li>Richness 4 (both lights) - As above but with foghorns. Sometimes you won't hear it for minutes, but a nice bass of a distant foghorn makes you feel like you're there.</li>
</ol>
As you can see you can really choose the right sound for you. Other sound therapy machines don't give you this flexibility. What if you don't like gulls on the ocean setting? With other machines it's tough luck!
