  1. Is Two Better Than One - The Benefits of BinauralAmplification It has been recommended that you purchase two hearing aids, but do you really need two? Are two really better than one? Well, that depends, but if you have hearing loss in both ears, this is probably so. Wearing two aids is called “binaural amplification”, while wearing one is called, “monaural amplification”. Binaural amplification has benefits, but not for everybody.Monaural (one ear) vs. Binaural (two ears) amplificationIf you were to decide to only purchase one hearing instrument, typically thataid is worn in the ‘better’ ear, or the ear that would best benefit fromamplification. For those with a hearing loss in both ear, binauralamplification is known to provide the best acoustic experience.There are several advantages to binaural amplification. Binauralamplification results in better listening in noisy or echo-y environments,helping understanding with competing sounds.Eliminates the “head shadow effect”. When listening with only one “good”ear, a listener often tends to turn the good ear closer to the sound source.However, when listening in a large group, this is not always possible.Therefore, the head “shadows” the sound from being received fully at theear furthest from the sound source. In cases where the good ear ends upbeing farthest from away great difficulty may be had to hear.Improves the signal-to-noise ratio. This means that the sound of interest isheard louder than background noise. When listening with two ears, thesignal to noise ratio is improved by 2 to 3 dB, making the sound of interestappear much louder than the background noise.

  2. This is very important for those who are having difficulty hearing insituations with a lot of background noise. Comprehension can be improveddrastically!Is your hearing loss is not the same on both sides? Maybe you even havenormal hearing on one side or no hearing on one side, and just do not seethe benefit of having two hearing instruments? There are special types ofhearing aid fitting which allow for some of the benefits of binauralamplification.In cases where there is normal hearing in one ear and an unaidable hearingloss in the other ear (or dead ear/no hearing) a Contralateral Routing ofSignal (CROS) hearing aid set could be appropriate. For those with a hearingloss in one ear and an unaidable loss in the other ear, Bilateral Routing ofSignal (BICROS) hearing aids would be more appropriate. Essentially, theCROS and BICROS configurations work by picking up sound from the poorerear, sending that sound on that side in addition to the sound being picked upat the better ear.Call a hearing healthcare professional today to learn about your options andtrial periods for your hearing aids!
