When powering up, turn them on last. This will reduce the chance of turn-on or turn-off thumps. • When connecting or disconnecting audio cables to and from a mixer or audio interface (both microphones or instruments), always make sure to turn down the main mix level as well as control room and headphone levels to avoid causing loudness in the headphones/ speakers. This will help protect your hearing. • Always make sure that phantom power (marked as 48V) is turned O FF when connecting/disconnecting a microphone cable. This will prevent yo u from damaging the microphone and your hearing. If the microphone you're using requires phantom power, make sure the microphone cable is connected first, before turning on 48V. • If you are recording in a room which also has speakers (like your home studio), always make sure to turn off your speakers before connecting any microphone. This will prevent feedback loops from occurring and damaging your hearing. • In a live venue with a PA system, always make sure to stand behind the main speakers when singing into a microphone. This will minimize the likelihood of feedback loops. Hearing Safety Tips California College of Music knows that your profession is heavily dependent on your hearing. As a musician you may be exposed to high levels of sound, sometimes for long periods of time, during rehearsals and performance as well as in the studio. Protecting your ears is critical to ensure many future years of m usic-making.

Frequently Asked Questions:
What's wrong with conventional earplugs?
AThey muffle speech and music.Conventional earplugs reduce sound more in the high frequencies than in the low and mid frequencies,which makes music and voices unclearand unnatural.Deeply-inserted foam earplugs can provide 30-40 dB of sound reduction,but only a small amount is typically needed.How much protection do people need?
AHearing loss is a function of exposure time,the average sound level, and the peak level of very loud sounds.Some persons are more susceptible to hearing loss from high-level sound than others.Most musicians do not need maximum protection,and many industrial workers can be adequately protected with as little as 10 dB of sound reduction.The majority of eight-hour-equivalent noise exposure in industry falls between 85 and 95 dB.Is there a non-custom high fidelity earplug?
AYes.Etymo tic Research designed and patented ETY•Plugs which are high fidelity ready-fit earplugs that reduce sound evenly by 20 dB atall frequencies,so that music and speech are heard clearly.Available in two sizes,for regular and small ear canals.Why are deep earmolds required for
Musicians Earplugs?
AEarmolds need to seal deeply in the bony portion of the ear canal or the wearer will hear a hollowor boomy sound in their own voice when speaking,singing or playing a brass or wind instrument.This unpleasant or distracting sound is called the occlusion effect.Deep earmolds (past the second bend of the ear canal) will eliminate this problem.What is the noise reduction rating (NRR)?
AThe U.S.Environmental Protection Agencyrequires manufacturers to print a noise reduction rating (NRR) on all non-custom earplugs. The formula used to determine NRR includes an adjustment for test variability,individual variability, and for those persons who do not wear ear protection as instructed.When worn properly,Etymotic earplugs provide more sound reduction than the assigned NRR value.Laboratory data on subjects wearing properly sealed ETY•Plugs shows between 18-22 dB average sound reduction over the 250-8000 Hz frequency range,but the NRR calculated from the same data is 12 dB.

the effectiveness of these earplugs and to reduce the occlusion effect.
