I highly recommend Hearing Science of Arcadia!!!!”
“They were on time for the appointment. When it came to the price of the hearing aids, she asked me, "How much do you want to spend?" I told her I don't like people to ask me how much do I want to spend, I don't know how much I want to spend and that's not their decision and I told her that. I had told her that Kaiser had done a hearing test, that was my first one and actually they had told me the left ear was different from the right ear so they'd done an initial test to make sure it wasn't something else. Then she tells me that I needed to get clearance from Kaiser. I didn't think that was necessary and it was a great inconvenience to go all the way to Baldwin Park so to me that was telling me she was incapable of making a decision on her own. If I would have never told her that, she would have made a decision, but since I told her that, now she making me make a decision so I never went back. ”

Hearing aids are small, electronic devices designed to amplify sound and improve hearing for individuals with hearing loss. They work by picking up sound from the environment, amplifying it, and delivering it into the ear. Hearing aids can be customized to fit the user's specific type and degree of hearing loss, helping to improve communication, speech understanding, and overall quality of life.
Hearing aids are an essential tool for improving the hearing and overall well-being of individuals with hearing loss. With advancements in technology, modern hearing aids are more discreet, comfortable, and feature-rich than ever before. Whether you're experiencing mild hearing loss or have more complex hearing needs, there is a hearing aid solution that can help you hear better and enhance your quality of life. Consulting with an audiologist is the best way to determine the most appropriate hearing aid for your specific needs and preferences.

Custom Earplugs and Hearing Protection
Our custom earplugs and hearing protection solutions help prevent potential damage to your ears. We specialize in:
Noise Plugs – Constant exposure to loud environments, whether in industrial settings, concerts, or bustling workplaces, can cause long-term hearing damage and fatigue. Our noise reduction earplugs are designed to provide effective hearing protection for anyone in high-noise situations, offering a comfortable, secure fit that reduces harmful noise levels without fully blocking environmental awareness.
These custom-fitted plugs are made with high-quality materials and tailored to fit your unique ear shape, ensuring optimal comfort and durability, even during extended wear. With a range of attenuation levels available, our noise plugs offer flexible solutions for diverse noise environments—from heavy machinery and construction sites to social events and public spaces. Protect your hearing and reduce noise-induced stress with our premium noise reduction earplugs, designed to keep you safe without compromising communication or awareness.
Shooting Ear Protection – Exposure to gunfire noise, which can reach levels as high as 140-190 decibels, poses a significant risk to hearing health. Proper shooting ear protection is essential to prevent both temporary and permanent hearing loss, as well as tinnitus, caused by high-decibel exposure. At Hearing Science, we offer custom-fitted shooting ear protection designed to reduce harmful noise levels while preserving environmental awareness for safe shooting.
Our custom shooting earplugs are crafted to fit comfortably and securely, providing superior noise reduction while allowing for clear communication and situational awareness. For frequent shooters, we recommend options with advanced technology, such as electronic filters, that provide dynamic sound management. These filters reduce gunshot noise instantly while letting in softer ambient sounds, making them ideal for both indoor and outdoor shooting environments.
Whether you’re a recreational shooter, hunter, or law enforcement professional, our range of shooting ear protection ensures effective and comfortable hearing protection tailored to your needs.
Musician Plugs – Musicians and music enthusiasts are often exposed to high decibel levels that can gradually damage hearing. Our musician earplugs are designed to protect your hearing while preserving the clarity and richness of sound, making them ideal for musicians, DJs, concertgoers, and anyone frequently exposed to loud music. Unlike standard earplugs, which can muffle sound, musician earplugs feature advanced filters that reduce volume evenly across frequencies, maintaining the natural quality of music and speech.
At Hearing Science, we offer custom-fitted musician earplugs that ensure a comfortable, secure fit tailored to your unique ear shape. These plugs provide varying levels of sound attenuation, allowing you to choose the amount of reduction that best suits your needs, whether for practice, live performances, or attending concerts. With our musician earplugs, you can enjoy every note safely, without sacrificing the details and dynamics that make music enjoyable.
Motorsport Plugs – Motorsports enthusiasts are frequently exposed to loud engine noise and wind turbulence that can lead to hearing damage and fatigue over time. Our custom-fitted motorsport earplugs are specially designed to reduce harmful noise levels while allowing riders and drivers to stay aware of surrounding sounds, such as communication devices or traffic cues.
These earplugs provide a comfortable, secure fit that stays in place even under a helmet, ensuring long-lasting protection without pressure or discomfort. Made from high-quality, durable materials, our motorsport plugs are crafted to withstand rigorous conditions and provide reliable noise reduction on and off the track. Whether you ride motorcycles, race cars, or participate in any high-noise motorsport, our earplugs offer essential hearing protection that enhances your focus and safety without compromising on sound clarity.
Swimming Plugs – Swim plugs, also known as earplugs for swimming, are specially designed devices used to prevent water from entering the ear canal while swimming or engaging in water-based activities. They are commonly used by swimmers, divers, or individuals who are prone to swimmer’s ear (otitis externa), which is an infection of the outer ear canal that can be caused by water exposure.
Custom-Made Earplugs: These are individually molded to fit the unique shape of your ear canal. They offer the best fit and comfort and are highly effective at keeping water out.
Surfer Plugs – Protection against exostosis ("surfer’s ear") and otitis externa (swimmer’s ear)
Sleep Plugs – Perfect for those with sleep difficulties or noise sensitivities
Each of our services is designed to address your unique hearing needs and lifestyle, providing quality care and advanced solutions to support your hearing health.
Sudden or prolonged exposure to loud noise can cause damage to your hearing and is one of the leading causes of hearing loss. This loss is often detected too late, meaning the impairment can be irreversible.
