That includes personal sound amplification products, or PSAPs.They can resemble hearing aids in their look, but hearing aids are commonly prescribed and used for those with significant degrees of hearing loss. PSAPs are lower cost and more accessible to buy because they're designed to enhance sounds for users without hearing loss. If you're curious about how PSAPs work or are thinking about getting one, here's what you should know before you buy. <h2>Who should use hearing amplifiers, or PSAPs</h2>Hearing amplifiers, or PSAPs, are designed for people who want to amplify sound for recreational use and have what is classified as "normal hearing" - or hearing thresholds of 20 dB or better in both ears. That makes hearing amplifiers ideal for people attending a lecture who may be stuck in the back, or a birdwatcher alone in a densely wooded park. If you're experiencing hearing loss and it's significantly impacting your day-to-day life, you should avoid PSAPs and opt for getting in to see a doctor about hearing aids. <h2>How PSAPs work</h2><div type="image" title="man with hearing device using phone" height="1412" width="1883" msid="82333752" hostid="261"></div>The main components of PSAPs are the microphone, speaker, amplifier, volume controller, and power source. The microphone captures pressure or sound waves and converts them into an electric signal, while the amplifier's electric circuit increases the extent and range of the signal. The speaker takes the amplified signal and converts it back into a sound wave. Volume controls let you adjust the amplification applied to the electric signal or sound, and the PSAPs battery power keeps the device working.PSAPs are universally sizable and depending on the model may require you to download an app to make setting adjustments. Typically, users can control the devices' volume levels, low and high mode amplification options, noise reduction, and settings for different listening environments through these apps.<h2>How hearing amplifiers differ from hearing aids</h2>Even though the two may seem similar, hearing amplifiers and hearing aids function in different ways. Since hearing aids are considered a clinical device, audiologists program and customize them for each person and their unique hearing loss pattern. "The main thing that distinguishes the hearing aid from the hearing amplifier is that hearing aids are fitted by audiologists," said <a href="https://oto.hms.harvard.edu/people/daniel-polley" target="_blank" rel="noopener">Daniel B. Polley, PhD</a>, a professor at Harvard Medical School. "They are programmed to simulate the biology of the inner ear a little bit more than a straight-up amplifier." Polley said that the signal processing of hearing aids is actually designed to mimic some of the features that are lost in an ear with sensorineural hearing loss. More specifically, the missing sensory cells naturally provided by your ear. An aid's compressive nonlinearity - or its technique for detecting and recognizing high-frequency sounds - then compensates for those cells. <div type="image" title="child being fitted for a hearing aid" height="1413" width="1885" msid="82333753" hostid="261"></div>This feature adjusts the hearing aids' dynamic range of sound, lowering the signals' gain or volume if they're too loud. It's similar to lowering the volume on a speaker when the sound levels are too loud to prevent distortion. Ultimately, a hearing aid can improve the dynamic range or intensify the loudness of a signal, which is encoded and converted by the hearing aid.In all, hearing aids undergo a lot of engineering to maintain sustainable battery life and power consumption. For someone who is experiencing gradual to extensive hearing loss, hearing aids are the better choice over hearing amps. <h2>What you should know before using a hearing amplifier</h2>Unlike hearing aids, PSAPs are not meant to be worn for extended lengths of time and aren't programmed to adjust to anyone's unique hearing loss patterns. In fact, they don't focus on heightening various ranges of sound, and instead simply amplify sound in all directions. As such, they aren't as complex as hearing aids, and that design simplicity is reflected in their more affordable cost. Without the need for a hearing evaluation or prescription, PSAPs can be purchased over-the-counter much like drugstore glasses. With PSAPs, users can control specific elements of their auditory experience through their device's mobile app, which offers different listening modes and filters. "PSAPs offer more control to the user," Polley said. "With hearing aids, the user trusts that the audiologist is going to set the aid to the needed settings." <div type="image" title="couple hiking with psap" height="1414" width="2121" msid="82333754" hostid="261"></div>While that kind of customization is ideal for many, you should also be careful when using it. If you do consider using PSAPs, Polley noted that hearing amps don't have directional microphones, making them susceptible to high levels of background noise. That means crowded environments like a noisy restaurant won't be ideal for hearing amplifiers but the quiet of your living room while watching TV may be. "I have used PSAPs when I go hiking. I love to amplify the sound with my feet crunching on the sticks with birdsong all around me," Polley said. "I feel super connected to nature when I'm amplifying all the sounds of the forest around me."<a data-type="6064f48fd26b7d2c380e7d48">Bluetooth speakers vs. smart speakers - the differences, pros and cons, explained</a><a data-type="5ffe24cde838ae3784373a7a">How to make your headphones louder in 7 different ways</a><a data-type="5e9f5b44a2fd912056297466">'What is Bluetooth?': A beginner's guide to the wireless technology</a><a data-type="5da9f16bcc4a0a146846e033">How to make your iPhone headphones louder in 3 different ways</a>

A total of 21 individuals were included in this study who had no experience of using hearing aid. AirPods 2 and AirPods Pro were connected with the iPhone XS Max smartphones with iOS version 13.0 for the study. The hearing performance of hearing aids and AirPods were then analysed to understand the similarity and differences between them in the study, which was supported by grants from the National Science and Technology Council, Veterans General Hospitals and the University System of Taiwan Joint Research Program. The electroacoustic features like maximum output sound pressure level at 90 dB sound, frequency response bandwidth, frequency response smoothness, and more were compared. AirPods Pro had the most similar features, whereas AirPods 2 met only some features in comparison to a hearing aid. The results of the study claim that AirPods Pro can be considered a good option to use by people who have mild-to-moderate hearing problems. The basic hearing aid device and AirPod Pro showed nearly the same performance, on the other hand, the AirPod 2 was not a good fit for this. Hearing aids are definitely the best solution to offer a better hearing experience but are available at a high cost and might require a medical prescription. Comparatively, Personal Sound Amplification Products like AirPods Pro, are easily available at a reasonable price, require no medical document and can assist in hearing better, making it a tempting option. Although the study does open up exciting possibilities for using AirPods Pro for its style, functionality, sound amplification features, and for countering social stigma associated with using hearing aids, it must be borne in mind that AirPods don’t meet the Food and Drug Administration standards to work as a hearing aid.
