Do We Really Need an Audiometric Booth?
You may be asking yourself, do we really need an audiometric booth? The answer is yes, but not for every application. Here are some common questions to consider. First of all, you should consider how much space the booth requires. It can be a significant amount of weight. If you need operator isolation, you'll need to consider a double room. Secondly, you should check the ambient noise levels in the area. However, with the advent of boothless audiometers, you don't need a booth, anyone, for a hearing test.

Audiometric exam booths are an excellent option for performing hearing tests in public schools, industrial settings, and mobile test vans. They are perfect for speech audiometry, and they can be locked down during the test. A boothless audiometer can also be moved to another location, thanks to lockable casters. The best thing about a boothless system is that it comes with built-in calibration systems and convenient software that can minimize paperwork. A daily printout of the verification can be kept for audit purposes. The use of earphones is another option for conducting audiograms. The earphones that are used for this purpose are called ER-3A insert earphones, and they reduce background noise by thirty to forty decibels. They are not the same as a traditional audiometric booth, but they provide the same type of benefits. These earphones will allow for a true audiometric zero test and will provide an accurate result. Another option is to use a computer-controlled audiometer. This device has earphones covered with circumaural protectors and monitors ambient noise levels. It will interrupt the test if the environmental noise levels exceed the pre-set limits. Audiometric testing requires a booth, but there are alternative methods that yield similar results. It's the noise level that's the key issue. So, do we really need an audiometric booth? In an experiment conducted by Buckey et al. in Tanzania, the average ambient noise level was three decibels lower than in the average American urban environment. It is, therefore, possible to perform audiometric tests in a similar environment without a sound booth. However, you should be aware that this method is not suitable for some applications. The objective of an audiometric test is to assess whether the hearing loss in a subject is caused by a particular noise. There is another option for audiometric testing: smartphone apps. Apps and headsets can perform the same testing as an audiometric booth. While traditional audiometers require a sound booth, smartphone headsets can also be used in clinical settings without a booth. They are not entirely practical solutions, but they can provide reliable results. Despite the obvious limitations of a traditional audiometric booth, it is a great way to bring audiometry into the community.
