Hearing is not always the same as understanding
Professor Flexer explains that audibility means speech can be heard, but intelligibility means speech is delivered clearly enough to be understood.
This difference is important in classrooms because a student may hear that a teacher is speaking, but still miss key parts of the message.
Why speech clarity matters in classrooms
Speech between 250 and 500 Hz carries much of the power of speech, but only a small part of its meaning. These sounds are often vowel sounds.
Consonant sounds, which usually sit above 2000 Hz, carry much more of the meaning of speech. These sounds are also easier to lose in busy classroom environments.
This means students may hear the teacher’s voice, but still miss the words that help them fully understand the lesson.
How soundfield systems support better listening
A soundfield system helps distribute the teacher’s voice evenly throughout the learning space. This allows students at the back, front and sides of the room to receive clearer speech.
The Redcat soundfield solution broadcasts vocal audio between 120 Hz and 13000 Hz, helping support clearer access to the teacher’s voice across the classroom.
Supporting students and teachers
Better listening conditions can help students stay engaged, follow instructions and take part in classroom discussions with more confidence.
For teachers, classroom audio technology can also reduce the need to constantly raise their voice throughout the day.
