Speech 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).

Recorded speech is a more accurate method of performing speech audiometry. Standardization of speech material is important for test and result reliability. The use of recorded speech stimuli as a standard of practice has been validated by many authors. (Mendel & Danhauer, 1997; Roeser & Clark, 2008)

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.

Design thinking - Making Sense of the Complex = Simple Paradox

Posted by Bernard Smith on Jan 17, 2018 10:00:00 AM

Humanity finds itself in a strange and sometimes frightening place in the 21st Century.

As we enter the fourth industrial revolution amid exploding research and development into artificial intelligence and robotics, where the man/machine interface is becoming closer and digital, the social landscape is full of paradoxes - one in which our ever-expanding global population is plagued by the phenomenon that while the rich get richer, the poor get poorer.

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!”.
