Both teaching and learning are highly demanding in acoustics. Poor acoustics in schools, lecture halls and classrooms may lead to having a negative impact on many students learning ability. Students who are reduced to learning in these types of environment struggle to understand what is being spoken. Extreme cases show that up to 70% of words spoken by teachers and lecturers cannot be heard by students, which makes concentration and understanding very difficult in learning.
Poor acoustics increase learning difficulties
Voices of teachers should easily and effortlessly reach around the whole classroom without them feeling any strain, teachers often lead discussions in the classroom so having a room with least possible background noise is paramount.
Classroom Acoustic Solutions
Sound levels being reduced is significant. Low frequency sounds around 125Hz are important to reduce as this enhances student’s ability to listen making listening comfortable for them. Low frequency sounds often interfere with speech clarity. When sound levels are reduced unwanted low frequency sounds are filtered out which allow listeners to hear the speech clearly.
Clarity of speech is preserved by restricting low frequency strong vowel sounds which then aids the consonant sounds. A speech reflecting zone would need to be in place with classrooms that are of a larger space and students are of a distance of 8 meters away from their teacher so they are heard at the back of the classroom.
Our ShushLiner wall panels when placed opposite the speaker will have a great effect on the overall speech clarity. Where suspended ceilings are not possible to install our ShushSky acoustic ceiling tiles are an excellent way to further enhance noise reduction.
An example of acoustic panels can be seen in our School Classroom project.
