Why Your Voice Sounds Big in the Bathroom

Many people love to sing in the shower. Their voices sound rich and full. But the same song in a bedroom sounds thin and quiet. What makes the bathroom so different?

The answer is in the walls. Sound is made of vibrations that travel through the air. When those vibrations hit something, they can bounce back. A bounce of sound is called a reflection.

A bathroom has hard, smooth walls made of tile, glass and shiny paint. Hard surfaces bounce sound very well. Your voice hits the walls and comes right back to your ears. It mixes with the sound you are making now. This makes your voice seem louder and longer.

A bedroom is full of soft things such as a bed, a rug and curtains. Soft things soak up sound instead of bouncing it. Fewer reflections come back, so your voice sounds plain.

That is why a room with no furniture sounds echoey. And it is why people who record music hang thick blankets or foam on the walls. They want to soak up extra bounces.

Plenty of people enjoy singing in the shower, where their voices sound rich and full. Yet the very same song sung in a bedroom often sounds thin and quiet. What could make the bathroom so different from other rooms?

The explanation lies in the walls. Sound consists of vibrations that travel through the air, and when those vibrations strike an object, they can bounce straight back. A bounce of sound is known as a reflection.

A bathroom is lined with hard, smooth surfaces such as tile, glass and shiny paint, and hard surfaces reflect sound extremely well. Your voice hits the walls and returns to your ears almost at once, blending with the sound you are making at that moment. As a result, your voice seems both louder and longer.

A bedroom, by contrast, is filled with soft furnishings such as a bed, a rug and curtains. Soft materials soak up sound rather than bouncing it back. Fewer reflections return to your ears, so your voice sounds plain.

This is also why a room with no furniture sounds so echoey. And it is why people who record music hang thick blankets or foam on the walls, since they want to soak up any extra bounces.

Ideas for class

  • Before reading, put reflection, vibration, tile, soak and echoey on the board with their meanings from the Words to know section and have students predict what the text will be about.
  • Read it aloud once while students follow along, then have them reread it alone or with a partner. At a calm 100 words a minute it takes about 2 minutes to read aloud.
  • Use the Read it big button (or B) to put the text on the projector, and Show answer on one question at a time so the class commits to an answer first.
  • Question 5 asks the reader to infer. Ask students to point to the words in the passage that led them to their answer.
  • Ask students to write one question the passage did not answer, then look for the answer in a book or on a classroom screen.
  • Print the student copy for independent work and keep the answer-key copy for yourself.
