By law, public places of gathering—from churches to movie theaters and event spaces—need to be accessible to everyone. The Americans with Disabilities Act (ADA) contains strict standards for audiovisual equipment that aim to ensure inclusivity for all. However, many establishments throughout the country fail to meet these standards today.
In this post, we’ll cover the basics of assistive listening, the standards outlined in the ADA, and how you can ensure compliance for your venue.
Firstly, What is Assistive Listening?
Assistive listening is a type of audio-visual technology that allows persons with a hearing impairment to participate in events and gatherings.
There are approximately 600,000 Americans who live with a severe hearing disability, and a further 6 million with a partial hearing disability. Fortunately, assistive listening devices come in many different forms. This gives every type of building or venue at least one option to consider when it comes to making sure they’re ADA compliant.
What Are Assistive Listening Devices?
Assistive listening devices (ALDs) are pieces of equipment designed to enhance the audio experience in public places for people with a hearing impairment. Typically they are found in movie theaters, conference centers, courtrooms, lecture halls, and houses of worship. Since they’re relatively discreet, the chances are that if you have never needed to request one, you probably won’t have noticed them. If you work in a public venue then you probably know that assistive listening systems aren’t always perfect. They can be inconsistent and difficult to use.
Thankfully, Media Vision offers a catalog of assistive listening devices if your current system is proving ineffective or difficult to maintain.
These systems, known as ‘hearing loops’, use an electromagnetic field to transmit sound. The T-coil inside a cochlear implant or hearing aid will pick up the signal from this field and amplify it. You may have seen signs showing an ear with the letter ‘T’ on them.
These systems transmit infrared (IR) light waves to users wearing portable IR receivers. Users will need to be within a line of sight to the receivers for them to work. IR systems are reliable but are more expensive than frequency modulation (FM) systems.
These are the most popular systems in the US, due to their affordability and ease of installation. They work by broadcasting a frequency modulation (FM) frequency, much like a regular radio. This is picked up by users wearing an FM receiver.
Does My Venue Need an Assistive Listening system?
Some venues are exempt from compliance with the ADA standards for assistive listening devices. However, you will need to be compliant if your venue meets the following criteria:
- Audible communication is integral to the use of the space
- The space uses an audio amplification system
- The space has an occupant load of 50 people or more
- The space has fixed seating.
There are some exceptions to these rules (for example, courtrooms require ADA compliance regardless of their occupant load). But if your venue doesn’t meet all of these criteria, you likely don’t need to do anything.
If your venue does meet all of these criteria, you will need to invest in an Assistive Listening system, if you don’t already have one. If you run a smaller venue, you might not need much in terms of equipment or infrastructure. However, you will still be legally obligated to provide equipment if and when it’s requested.
The amount you will need is determined by the seating capacity of your venue. The more seats in your venue, the more assistive listening equipment you’ll need.
What Are the Penalties for Non-Compliance?
Federal law allows for fines of up to $75,000 for a first violation and up to $150,000 for additional violations.
However, local and state law may require additional, higher standards of accessibility than is specified in the ADA. We recommend getting in touch with an attorney in your state if you’re unsure about your local standards.

ADA Standards for Assistive Listening
There are several technical standards that need to be met to ensure compliance. These standards have been designed to ensure that the user experience is simple and problem-free:
- Receiver Jacks
Receivers need to include a 1/8 inch (3.5 mm) standard mono jack.
- Signal-to-Noise Ratio
The signal-to-noise ratio for internally generated noise in assistive listening systems needs to be 18 dB minimum.
- Receiver Hearing-Aid Compatibility
Receivers need to interface with telecoils (T-coils) in hearing aids through the provision of neckloops.
- Sound Pressure Level
Assistive listening systems need to provide a minimum sound pressure level of 110 dB and a maximum of 118 dB. The volume control range needs to be at least 50 dB.
- Peak Clipping Level
Peak clipping can’t exceed 18 dB of clipping relative to the peaks of speech.
In addition to these technical standards, ADA guidelines also require the appropriate signage, letting people know that an assistive listening system is in place. The signage must feature the International Symbol of Access for Hearing Loss.
