Many believe to have a clinically valid audiometric test; it must occur in a sound booth. They believe it is necessary to eliminate any background noise and possible distractions that could lead to inaccurate test results. However, recent advances in audiometric technology are enabling a shift to test outside of the booth. This shift is being widely embraced by both hearing healthcare professionals and patients alike.
In addition to expanding available and appropriate hearing testing locations, there are also advantages to testing outside of a sound booth. This can include a better patient experience for those uncomfortable in confined or air-tight spaces, and a better clinician-patient connection during testing which can be especially helpful for those for whom hearing testing is stressful. From a business perspective, maximizing clinic spaces other than the booth can help increase the return on investment on room space, and can help lower the wait times for basic evaluations, not to mention providing a viable option for those unplanned additional tests or ENT Clinic add-ons.
Patient Experience: Some patients feel claustrophobic and uncomfortable while seated in a small, soundproof audiometric booth. An anxious patient may not provide optimal results because they are worried or preoccupied.
“If I feel that my patient is struggling during the testing session, I’m going to do my utmost to make them as comfortable as possible. I might opt to use tablet-based SHOEBOX, which is an audiometer optimized for use outside of a sound booth so that I can continue to be in the same room as that person to provide them additional encouragement and support,” explained Renée Lefrançois, Director of Audiology at SHOEBOX.
Additionally, mobility constraints of a sound booth may be problematic for patients that require assistance. To achieve effective sound blockage from the outside, many double-walled sound booths have a door ledge or series of ledges that can be hazardous. A typical sound booth floor area is approximately 8 square feet or less. Maneuvering can be a concern for some patients with a disability, especially with the added requirement of a wheelchair or walker.
Increased Efficiency: SHOEBOX makes it easy to perform hearing testing and screening that can power a wide range of processes. These workflows can include fully remote screening, mobile diagnostic testing, and automated basic testing. Using SHOEBOX’s pre-screening products can help to determine who to prioritize to ensure a full diagnostic test only for those who need it.
In addition, in a busy clinic, every day is different. Every patient’s needs are different. Sometimes you have add-on patients, especially in ENT clinics. These patients come in for a medical evaluation but may have erroneously not been scheduled for a hearing test. SHOEBOX is ideally suited as a solution for add-on patients that may have had to otherwise wait months for an appointment.
Backlog Issues: The investment in a sound booth is high. “There are some inherent problems associated with audiometric sound booths. The first and most obvious is the cost of the device; typically starting at $4,000.” (Alberto Behar, 2020).
In addition, the square footage a sound booth takes up in a clinic is costly. “The more sophisticated the booth is, the more space it requires, as is its mass. If there is a need also to isolate the audiometric operator, then a double room is required, and more space has to be allocated.” (Alberto Behar, 2020).
With the average U.S. retail space renting for approximately $23.00 per square foot, this is valuable real estate that could be used for more profitable activities. Supplementing the clinic’s existing sound booth with SHOEBOX audiometric testing allows more patients to be tested without incurring the cost of another sound booth.
Save Money: Patient no-shows are a costly problem, both for providers as well as for patient outcomes. The Ontario 2020 hearing test fee guide suggests $147 for complete hearing assessments and $120 for hearing aid recommendations. So if a patient misses a sound booth appointment, instead of waiting months to be re-booked, they can quickly be scheduled for a mobile test to determine the need for more diagnostic testing.
Other cost necessities include calibrations and upkeep of the room itself. ANSI requirements state that calibrations of a sound booth take place annually. In addition, over time, the booth itself will get older and require general maintenance. Some studies claim that a significant percentage of the booths currently being used for hearing testing do not comply with the audiometric standard requirements.
Another costly consideration with respect to enclosed sound booths is the need to disinfect the area, and the air quality, between patients. A typical sound booth appointment can take up to an hour to complete and based on the clinic’s ventilation systems may require 15 – 20 minutes between patients. The room must be cleaned, disinfected, and ventilated between each patient. Mobile testing can be used in alternate quiet rooms in the clinic throughout the day to help bridge those timing gaps.
The Canadian Audiologist Journal states, “Results of studies support the use of alternative means that allows obtaining similar results to a sound booth. The key issue is maintaining and controlling the background noise levels so that the hearing of the subject being tested is not affected.” (Alberto Behar, 2020).
SHOEBOX Audiometry incorporates several sets of Maximum Permissible Ambient Noise Levels (MPANLs) to choose from depending on the test environment (ANSI or OSHA). Should these levels be exceeded during a testing session, SHOEBOX will alert the administrator with several types of configurable notifications.
SHOEBOX is an ideal complement to the in-clinic booth with its ability to conduct accurate audiometric assessments in any relatively quiet environment, improving processes with new workflows, creating a pleasant alternative to an enclosed sound booth all while lowering expenses.
There are several key benefits to adding boothless testing to your clinic offering; the bottom line is that SHOEBOX Audiometry offers you multiple noise-monitored testing options to help you better meet the needs of your patients.
