Q&A: Speech Audiometry - With Dr René Hornby

Posted by Hlolo Ramatsoma on May 24, 2018 11:48:49 AM

Speech is the auditory stimulus through which we communicate. Auditory assessment using speech is therefore of great interest in the field of speech and hearing sciences; in fact, it has a long history in the evaluation of hearing from as early as the 1800s. Auditory assessment using speech has been studied as early as 1804, but the validity and reliability of speech testing is as important today as it was then.

When Helping Hurts

Posted by Hlolo Ramatsoma on May 17, 2018 11:34:50 AM

The audiologist can be a solitary species. Choosing to lose ourselves in our work and focus on patient care instead of the heady social life we see zooming around us. Maybe it's because we are very focused, or perhaps it's because many of us are in some ways introverted. After all, this is the path we chose and we are sticking to it.

Calibration Is As Important As Exercise, But Why?

Posted by Hlolo Ramatsoma on Apr 25, 2018 3:16:45 PM

We are all acutely aware of the fact that in order to stay healthy we need to exercise. We are especially aware after a long cold winter or summer holiday. While the list of benefits we gain from physical activity including longer life, improved vitality and weight-loss, many of us still don't do it.

Speech testing in Audiometry: Recorded vs. Monitored Live Voice

Posted by Hlolo Ramatsoma on Apr 19, 2018 8:54:25 AM

Of the many hearing tests, speech is one of the most fundamental in the test battery. Unfortunately, it has been shown to be one of the tests that audiologists conduct without using procedures that have been shown to be valid and reliable (Martin & Pennington, 1971; Martin & Forbis, 1978; Martin & Sides, 1985; Martin & Morris, 1989; Martin et al, 1994, 1998; Wiley et al,1995). The continued use of monitored live voice (MLV) for speech stimuli presentation is prevalent , despite ample literature indicating why recorded speech should be preferred. (Carhart, 1946, 1965; Brandy, 1966; Kreul et al, 1969; Penrod, 1979; Hood & Poole, 1980; Mullennix et al, 1989; Roeser & Clark, 2008; Wilson & McArdle, 2008; Katz, 2014).

What You Need To Know For Successful Masking In Audiology

Posted by Hlolo Ramatsoma on Apr 3, 2018 1:05:52 PM

Breath in.. Breath out..

Most clinicians break out in a cold sweat when it comes to masking in audiology. “Am I doing this correctly, is it effective?”. Take a deep breath and look no further.

To understand masking, we must first understand the science behind it. We must also cover some of the related concepts such as interaural attenuation (IA) and the occlusion effect (OE). You may already know of these terms, but let’s see if we can shed a little light on how they all work together.

8 Audiology Jobs Audiologists Should Know About

Posted by Hlolo Ramatsoma on Mar 26, 2018 5:26:17 PM

Some may think of audiologists as people who fit the elderly with hearing aids. While this may be partly true, it is a vast simplification of what audiologists actually do. 

Audiology is a varied and complex profession requiring in-depth anatomical and physiological knowledge. It is demanding and requires commitment to quality patient care, empathy, careful counseling and patience.

A Bone to Pick with Bone Conduction

Posted by Hlolo Ramatsoma on Mar 19, 2018 8:30:00 AM

Just over 70 years ago, Georg von Békésy’s experiments laid the foundation for bone conduction (BC) testing. Over 50 years ago, Raymond Carhart researched and wrote about the clinical applications of BC assessment. Ever since the earliest testing using tuning forks, the assessment of bone-conducted hearing sensitivity has been an essential part of audiological assessments and remains so today.

Ambient noise attenuation: the key to reliable hearing assessment

Posted by Hlolo Ramatsoma on Mar 2, 2018 1:47:45 PM

Have you ever experienced loud interfering background noise during testing? Has it ever been so loud that testing had to stop?  Well, you are not the only one.  Background noise, also known as ambient noise, is a huge concern as not only can it affect the quality of your results, but can also create a knock on effect for the patient.

Deaf or Death? A New Answer to Ototoxicity's Oldest Question

Posted by Hlolo Ramatsoma on Jan 16, 2018 12:11:02 PM

Ototoxicity is the negative effect of certain medications that can cause hearing loss. Even common medication such as Aspirin or ibuprofen pose a risk.  It is well documented but largely ignored and rarely discussed. If you have ever found yourself advocating for ototoxicity monitoring, a question such as “Would you rather the patient die or go deaf?” will not likely be new to you.  While this argument has historically carried validity, advancements in both technology and medication alike offer a new and more helpful answer, “Neither!”.
