Hear or listen

In a classroom the teacher speaks and the students are supposed to listen, understand and memorise what they have learned. But what happens if students have difficulty hearing what the teacher is saying?

Create good sound environments for educational spaces by:

  • reduce the sound levels
  • ensure short reverberation time
  • ensure speech clarity

There is a difference between hearing and listening. Hearing is passive – when the sound waves hit our eardrums we hear. Our hearing is turned on 24 hours a day, we even hear when we sleep. Listening is active – when we hear something that we think seems interesting, we start listening.

In a classroom with a good sound environment it is easy for the students to listen to the teacher. But if the students are disturbed by other sounds, it becomes more difficult.

A sound environment for learning

In a classroom with a poor sound environment, the students need to put effort into listening. This requires energy or “brain power”. Studies show that when the working memory is burdened with identifying what is being said, there is not so much energy left to understand and remember the information that has been shared by the teacher. This is one of the reasons why students in a poor sound environment:

  • experience a reduction in short-term and long-term memory
  • are less focused
  • have lower reading ability
  • lower test scores

 

Create a sound environment for learning

To create a good sound environment for educational spaces, it is important to reduce the sound level, ensure a short reverberation time and ensure speech clarity.

Check mark Use a sound-absorbing ceiling with the best absorption qualities at all frequencies. Pay extra attention to the ceiling's performance in the lower frequencies (125 Hz) since low-frequency sounds distort speech and make communication harder.

Check mark A suspended wall-to-wall ceiling will generally perform better in the lower frequencies that a direct-fixed ceiling or free-hanging units. A thicker absorbent generally absorbs more sound energy than a thin one, reducing the noise level more effectively.

Check mark Despite the use of a class A ceiling there can be intrusive reflections from the walls. Add wall absorbers on the back wall opposite the speaker to reduce the echoes and improve the speech clarity further.
