Hearing Aid Specialists

Welcome to St Wojciech’s Hospital Hearing Aid Specialists Clinic in Poznań, where our patients can use the following services:

1.Basic hearing tests

• PURE TONE AUDIOMETRY (PTA)
  A hearing test used to identify the hearing threshold of the patient. During the test an individual is supposed to respond to pure tone stimuli of different frequency and intensity by signaling their reaction and pressing the button the moment they hear the tone in headphones.
• IMPEDANCE AUDIOMETRY (TYMPANOMETRY)
  An objective hearing test which examines the condition of the middle ear, which consists of two parts:
  tympanometry – determines the mobility of the eardrum
  the stapedius reflex (acoustic reflex) – a mechanism that protects the cells from high-intensity sound stimuli through involuntary muscle contractions.

• SPEECH AUDIOMETRY
  A test determining the number of words heard and understood correctly depending on the level of sound intensity.
  Our offer also includes a number of supra-threshold tests which enable to locate the exact area responsible for a given hearing impairment:
  SISI – Short Increment Sensitivity Index Test (a test designed to find out whether the patient can hear very small changes in sound intensity);
  Langenbeck’s test – evaluation of the perception of tone while presenting noise;
  Fowler’s test – alternate binaural loudness balance (ABLB);
  TDT – tone decay test;
  Sullivan’s test – assessment of balance and mobility of the stapes.

Additionally, we perform specialized hearing tests, such as otoacoustic emission (OAE) and auditory brainstem response (ABR).
ABR (BERA, auditory brainstem response) is a non-invasive, objective examination, which allows to diagnose hearing loss and enables precise determination of the areas responsible for hearing impairments. Since this examination does not require cooperation between the patient and the audiometrist, it is most often used to verify the ability of hearing in the youngest patients (the test can be done in the child’s natural sleep). However, it is also used to find out the causes of a sudden loss of hearing in adults.

2. Purchase of hearing aids
We offer a wide range of BTE hearing aids and ITE models that are almost invisible when worn. The most recent developments in this area allow for a wireless transmission of the sound wave from mobile phones directly to the hearing aids, guaranteeing a discreet use of the device thanks to a dedicated app. A powerful battery enables the device to run without recharging for one week up to several weeks.
