WideBand Tympanometry
The latest version of the GSI TympStar Pro™ includes a new higher resolution touchscreen, WideBand Tympanometry testing* and hardware changes that make the device faster. Utilizing a new stimulus, WideBand tympanometry (WBT) consists of an automatic sequence of measurements that provide a comprehensive set of data on the status of the middle ear while at the same time using the same test procedure as traditional tympanometry.
The TympStar Pro automatically displays tympanograms at 226, 678, 800, and 1000 Hz along with a WideBand Averaged Tympanogram that is calculated over a select number of frequencies. The WideBand absorbance test shows how well the middle ear absorbs sound across the frequency range.

Webinar Series
Jackie Davie, PhD | AudiologyOnline | CEU-Eligible
In this on-demand, three-part series, Dr. Davie shares her wealth of knowledge with over a decade of WBT research. In this series, you will be challenged on the traditional tympanometric classifications and encouraged to dive deeper into the power of WideBand Tympanometry
Beyond the Basics: Interpreting Wideband Tympanometry with Confidence
Wideband tympanometry is a powerful tool—if you know how to use it. Join this session to learn practical interpretation techniques and gain the confidence to integrate WBT into your daily practice.
Beyond Type A, B, and C: Normalizing Mass, Friction, and Stiffness-Dominated Language in Wideband Tympanometry Middle Ear Assessment
Mass, stiffness, friction dominance—these terms get tossed around in ME pathologies, but how well do we really use them? Let’s cut through the noise: revisit the core concepts, apply them to real clinical cases, and sharpen your day-to-day interpretation skills.
Advancing Middle Ear Assessment: What Otolaryngologists Need to Know About Wideband Tympanometry
Wideband tympanometry (WBT) is more than just data—it’s diagnostic power. This session gives you and your physicians the essential tools to confidently interpret WBT results and make clearer calls on middle ear disorders. Turn complexity into clarity with practical, clinical insight.
One pressure sweep of the wideband click results in the automatic calculation and display of:
- Tympanograms at 226 Hz, 678 Hz, 800 Hz and 1000 Hz probe tones
- Tympanic peak pressure (TPP), ear canal volume (Vea), and admittance for each probe tone
- WideBand averaged tympanogram
- Middle ear absorbance across the frequency range
- Age specific normative data for absorbance at tympanic peak pressure (TPP) and ambient pressure
When using WideBand testing on the TympStar Pro, users can gather a full set of tympanometry data in the same time that it would take to do a single 226 Hz sweep. WideBand tympanometry can be used for infants to simultaneously obtain tympanograms at both 226 and 1000 Hz for accurate interpretation. Age-specific normative data is included, and can be customized, to provide an easy visualization of the test results that clinicians can share with their patients for counseling purposes.
Results include an absorbance graph, which shows how much sound is absorbed by the middle ear from low to high frequency. The absorbance pattern in an ear with normal middle ear function differs considerably from ears with middle ear pathology. Examples of absorbance tracings for common middle ear pathologies such as otosclerosis, middle ear effusion, and discontinuity of the ossicular chain are provided and can assist in test interpretation.
