Why does my singing sound better in the shower?

Hi, my name’s Caitlin and I’m a shower singer. Well, let’s be honest, I sing a lot, and not necessarily very well, but I do enjoy it.  And I’m sure that most of you, like me, have noticed that you sound a lot better in the shower than anywhere else.

Is it a psychological thing? With no-one there to judge you, do the insecurities holding you back disappear, unleashing your true singing potential? Well, sadly, no. There are three main reasons your voice sounds better in the shower, and they are all to do with the shape of your shower, and the material it’s made up of.

Most showers are made of tiles and other hard, non-absorbent surfaces, and they are usually enclosed rectangles. When we sing – or talk, shout or gargle for that matter – we create soundwaves. Different notes have different frequencies depending on whether they are high or low. High notes have faster frequencies (like the purple line in the image below) and low notes have slower frequencies (like the red line).

Sound waves of different notes have different frequencies

When we create these sound waves, they will travel out of our mouths until they hit something. In a shower, they very quickly find a nice sound-reflecting surface – your tiles.  Rather than escaping, the sound waves bounce around your shower, and becomes louder as there are more sound waves hitting your ear. This is the first reason your voice sounds better in the shower – more volume = a more powerful sounding voice.

The second reason is very closely tied into the last one. Well lets be honest, in a shower, everything is pretty close to everything else. In addition to making the sound louder, all these sound waves bouncing off the walls create an affect known as reverberation or just reverb. You’ve heard it before, it’s what karaoke machines do to try and make people seem not quite so terrible.

Reverb is essentially a whole lot of echoes all very suddenly. If you were in a cave (and why wouldn’t you be?) the echoes come off the cave walls which are usually rather far away. In a shower, they’re nice and close, and you get a lot of echoes all at once. In addition to giving a nice echoey sound which you can hear here: An Example of Reverb – it also smoothes out the pitch of your singing. They noise becomes somewhat blurred, and so you even when your notes are as wobbly as jelly, they sound like they’re stable. This won’t help if you’re singing half an octave off key, but if you’re already close this makes it even better. So secret number two to shower singing – reverb!

The final trick to sounding better in the shower is resonance. Because of the distance between the walls of the shower, certain sound wave frequencies are amplified more so than others. In showers these tend to be nice low bass notes, which gives your voice a nice rich quality.

Remember, having a shower curtain instead of a solid door, or having something softer than tiles on the walls can reduce the impact of all of these.  MOST importantly, reverb only applies INSIDE the shower, so anyone listening to you from outside will hear a much louder but probably rather wavering voice. In fact, because you pitch your singing off what you can hear, the reverb is actually tricking you, and you will most likely actually be singing even less in tune than normal. So beware of anyone else lurking outside when you start shower singing!

So there you have it – Volume, Reverb and Resonance, all working together to make you sound like a pro. Leave a comment and be sure to watch out for the next post on Science MIA!

  2. Wow! I thought it was all psychological. This has really helped with a science fair project I’m doing “Why do I sound better in the shower”.

    Thanks.

    Well I guess there goes my idea of singing in the shower on stage if I would sound worse
    But at least now I have an answer
    THANKS

    This is such a great article. I enjoyed reading this. Thanks.

  7. This is the same reason why voices sound better in a parking ramp? The walls aren’t close, but the same things seem to apply. So I’m not only not singing better in the parking ramp, but might actually be singing worse? I had guessed that the resonance was making my singing sound better by giving me feedback. Still, I do like the way it sounds in the garage.

  8. Everyone loves it when people come together
    and share thoughts. Great site, stick with it!

  9. I was just singing in the shower a few mins ago at the top of my lungs and I was really rather impressed. Not because I sounded really good, but because I didn’t sound as appalling as usual. I just had to google the question and found your blog- so thanks!

  13. I thought it was because the steam lubricated my throat and voice box better. It doesn’t just sound better, it comes out better. It’s much easier to sing higher notes in the shower and that’s not something that can be accounted for by echo I don’t think. My voice cracks less and the notes come out incredibly smoothly, which normally isn’t always perfect even when I’ve been warming up for a while, but in the shower it pretty much is perfect.

    I always thought it was because no one was there to judge you. That could be it as well I suppose!
