Hearing Augmention Part II - The Pros and Cons

In part one of this series, we discuss what hearing augmentation is, the type of technology available for your workplace and why you need it. In part two, we will unpack the pros and cons of each technology including the cost, functionality, and maintenance.

Induction Loop Systems

An induction / Audio Frequency (AFIL) / hearing loop system transmits an audio signal directly into a hearing aid via a magnetic field.

‍

PROS

Low maintenance

No receivers are required, just the users hearing aid (No obvious disability discrimination)

Sterile and COVID safe, as the personal hearing aid is used only.

‍

CONS

Expensive to buy and install

Not all hearing aids (especially newer models) have a T-mode / T-switch

Metal floors/ceilings cause interference and/or signal loss

Loop can easily be cut during installation of carpet or other surfaces

Very difficult to retrofit

‍

IR Systems

An IR system uses infrared light to transmit an in-room audio signal source from a transmitter mounted locally within the room to a receiver worn by the user.

‍

PROS

Moderate cost

Secure and confidential as line-of-sight is required to the transmitter (as long as windows to the room are not transparent)

Users without hearing aids can use the system as well via infrared headsets

Easy to retrofit

‍

CONS

A receiver is required to use the system and worn on the user's body (disability discrimination)

Public health concerns as receivers are shared amongst users (sterilisation is required)

Ambient light can interfere with the infrared signal

‍

‍

FM Systems

An FM system uses frequency modulated radio waves to transmit an in-room audio signal source from a transmitter to a receiver worn by the user.

‍

PROS

Low cost

Users without hearing aids can use the system as well via infrared headsets

Easy to retrofit

‍

CONS

Not secure as the FM signal can be picked up by anyone who “tunes-in” to the frequency being modulated.

A receiver is required to use the system and worn on the user's body (disability discrimination)

Public health concerns as receivers are shared amongst users (sterilisation is required)

‍

‍

WiFi Systems

Utilising an existing or new network infrastructure to transmit an audio signal source over WiFi to a user's personal mobile device.

‍

PROS

Low cost to install and low maintenance

Secure and confidential as audio channels can be password protected and changed regularly.

No receivers required, just the users hearing aid (No obvious disability discrimination)

Can leverage existing network infrastructure / WiFi

Sterile and COVID safe, as the personal hearing aid and/or personal device is used only.

In-app advertising / promotional opportunities

Options beyond hearing augmentation.

‍

CONS

Depending on requirements, may be expensive to buy

Not everyone has a mobile phone.

Additional WiFi access points may be required to ensure the best coverage across the space / building
