Young students have a right to quiet zones for study, teaching and examinations however classroom noise in schools, colleges and universities is on the rise.<\/strong><\/p>\n\n\n\n<p class=\"has-text-align-left wp-block-paragraph\">In recent studies[1] daily noise exposure for young people in schools in the UK averaged 72dB(A); classroom conversation alone frequently takes noise levels above the 35dB(A) WHO recommended level for background noise during teaching sessions and above the 55dB(A) recommended maximums for background playground noise. <\/p>\n\n\n\n<p class=\"has-text-align-left wp-block-paragraph\"><strong>This excessive noise can be detrimental to students\u2019 performance as high levels of background noise interfere with hearing and concentration in the classroom. <\/strong><\/p>\n\n\n\n<p class=\"has-text-align-left wp-block-paragraph\">These high noise levels can also be detrimental to teachers hearing where hearing loss and tinnitus are common, for instance, a recent Swedish study[2] found that seven out of 10 female preschool teachers suffer from sound-induced auditory fatigue, one out of two has difficulty following speech, and four out of ten had become hypersensitive to sound.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The noise outside the classroom is also an issue.<\/strong> For example, excessive noise in corridors during exam time will be a distraction to those undertaking examinations, or it can cause interruptions to normal classroom teaching.<\/p>\n\n\n\n<p class=\"mt-5 wp-block-paragraph\">Of course, it is not just noise generated by students that is of concern in teaching environments. Power tools and machinery used in teaching, for example in metal or wood-working workshops, noise in music rooms, and the noise from building services, maintenance and grounds-keeping are also of concern because of the potential impact of noise-induced hearing loss. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is not just students that are affected; the Noise at Work Regulations govern the legal limits for exposure to workers from <a href=\"https:\/\/pulsarinstruments.com\/solutions\/workplace-noise-monitoring\/\" data-type=\"solutions\" data-id=\"481\">occupational noise<\/a>, so all employees involved in activities that exceed the noise action levels must be protected.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column p-5 has-background is-layout-flow wp-block-column-is-layout-flow\" style=\"background-color:#ecf4ff\">\n<h5 class=\"wp-block-heading\">Key noise level problems:<\/h5>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Noise from other students can be a distraction from studies in classrooms.<\/li>\n\n\n\n<li>Noise in corridors during exams or in other quiet zones breaks concentration and affects learning.<\/li>\n\n\n\n<li>Noise in classrooms leads to increased stress and the teacher having to raise their voice louder. It also leads to a negative feedback loop of noise; to hear what&#8217;s being said young people have to talk louder and louder. This could in the long term affect students and teachers hearing.<\/li>\n\n\n\n<li>Noise at work impacts on students from machinery or power tools in college workshops or on employees from maintenance and grounds keeping works.<\/li>\n\n\n\n<li>Exposure to noise in school music facilities where music teachers and students can be exposed to high occupational noise levels above legal limits.<\/li>\n\n\n\n<li>Poor classroom acoustics: lots of hard and reflective surfaces bounce noise around.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n\n\n\n<h4 class=\"wp-block-heading\">Solutions for noise in schools, colleges and universities<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>So, how do you control noise in schools? <\/strong>There are several options. You can use noise level meters such as the <a href=\"https:\/\/pulsarinstruments.com\/products\/model16-entry-level-sound-level-meter\/\" data-type=\"product\" data-id=\"452\">Pulsar Model 16<\/a> to do quick spot checks on noise levels or use the <a href=\"https:\/\/pulsarinstruments.com\/products\/nova-basic-sound-level-meter\/\" data-type=\"link\" data-id=\"https:\/\/pulsarinstruments.com\/products\/nova-basic-sound-level-meter\/\">Pulsar Nova<\/a> to determine and report on the noise levels in classrooms and workshops. If noise levels exceed recommended levels then a noise action plan should be produced.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>You can create quiet zones in classrooms, corridors, exam rooms and libraries using the Pulsar SafeEar <\/strong>\u2013 a noise-activated warning sign that lights up to tell people when a pre-set level of noise has been exceeded and noise levels need to be reduced. The <a href=\"https:\/\/pulsarinstruments.com\/products\/c\/noise-activated-warning-signs\/\">Pulsar SafeEar<\/a> noise warning signs only illuminate when noise levels are exceeded so they are perfect for areas with varying noise levels.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">[1] Studies conducted by Southbank University and <a href=\"https:\/\/www.ucl.ac.uk\/ioe\/\" target=\"_blank\" rel=\"noreferrer noopener\">Institute for Education<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">[2] Hearing-related symptoms among women &#8211; Occurrence and risk in relation to occupational noise and stressful working conditions, <a href=\"https:\/\/sahlgrenska.gu.se\/english\" target=\"_blank\" rel=\"noreferrer noopener\">Sahlgrenska Academy, University of Gothenburg<\/a>, June 25 2018. <a href=\"http:\/\/hdl.handle.net\/2077\/55969\" target=\"_blank\" rel=\"noreferrer noopener\">http:\/\/hdl.handle.net\/2077\/55969<\/a><\/p>\n","protected":false},"featured_media":548,"template":"","format":"standard","class_list":["post-485","solutions","type-solutions","status-publish","format-standard","has-post-thumbnail","hentry"],"_links":{"self":[{"href":"https:\/\/pulsarinstruments.com\/de\/wp-json\/wp\/v2\/solutions\/485","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pulsarinstruments.com\/de\/wp-json\/wp\/v2\/solutions"}],"about":[{"href":"https:\/\/pulsarinstruments.com\/de\/wp-json\/wp\/v2\/types\/solutions"}],"version-history":[{"count":3,"href":"https:\/\/pulsarinstruments.com\/de\/wp-json\/wp\/v2\/solutions\/485\/revisions"}],"predecessor-version":[{"id":20975,"href":"https:\/\/pulsarinstruments.com\/de\/wp-json\/wp\/v2\/solutions\/485\/revisions\/20975"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pulsarinstruments.com\/de\/wp-json\/wp\/v2\/media\/548"}],"wp:attachment":[{"href":"https:\/\/pulsarinstruments.com\/de\/wp-json\/wp\/v2\/media?parent=485"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
