environment is a safe and healthy one. Don’t work hard to improve physical health at the expense of your hearing health. Here are some tips to help you deliver great workouts without causing hearing damage to yourself or participants: • Measure your noise levels. The facility you work in may invest in equipment such as the SoundEar, or you may download a smartphone app that gives accurate noise level readings. • Consider how many classes are taught each day and by whom – share the dose load to keep everyone safe. • Use this table to work out the safe noise limit for your classes. Noise level (LAeq) Maximum Daily Exposure Duration 85 dB 8 hours 88 dB 4 hours 91 dB 2 hours 94 dB 1 hour 97 dB ½ hour • Mark the safe volume on your sound system and stick to it! • If you are the group exercise manager or facility operator, conduct regular audits – maybe once every three months. Make sure instructors are part of the process and make adjustments if you need to. • Experiment with tempo, visual stimuli and volume variation to get your clients moving and keep them motivated. • Talk with your clients and explain any changes and why you’re making them. Get feedback from all your clients – not just those who are the most vocal! Remember, your hearing health is in your hands. By turning it down a notch, not only will you avoid hearing damage, you’ll also be better meeting the needs of your clients, and ensuring a truly healthy environment for all gym users. What does Les Mills say? Regarding volume in classes, Michelle Dean, training manager at Les Mills Asia Pacific, says: ‘When it comes to the volume of music within a club, this is something that is managed between the instructor and the club. If anyone is unsure about what the optimal volume should be, we recommend SoundEar – a tool that enables a club to measure and manage the noise level within their gym environment.’ ‘Through ongoing education of our Instructors we teach them the importance of using their voice correctly – warming up, not shouting and how to deliver an amazing workout vocally without damaging their vocal cords. In addition to this, we educate them around the importance of a microphone and how to use it effectively when instructing classes.’ Elizabeth Beach is a researcher at the National Acoustic Laboratories. She began working in the area of hearing loss prevention after completing her PhD in psychology. Her main area of research is leisure noise, its contribution to overall noise exposure and how it might be affecting our hearing acuity. [email protected] AT LAST - A LOW COST LOUDNESS MONITOR! Know how loud it is in every studio. Fitness Audio have just released their LM-30 Loudness Monitor called “The Trigger”. It measures the ambient noise level in any area like a group fitness studio. There are two multi-coloured bars to show how loud it is - 3 red LEDs means it’s at the max. Mount it on a wall between loudspeakers and set it at a level from 79dB to 109dB in 3 dB steps in either “A” or “C” weighting. Connect it to a power point for just a visual loudness display. Or, link it with CAT 5 cable to our SPL2.2 Sound Pressure Limiter - “The Gov^nor”, not only to power it but also to send a signal that tells the limiter to cut in because it’s too loud! The Trigger and The Gov^nor working together all day long will keep the sound at a predetermined level. This is just what all club owners need Combo to save on amp and speaker repairs and keep members and neighbours happy. Price $297*ly *LM30 on $792 PANTONE 165 C PANTONE 661 C A
