Elimination of Ambient Noise The GSI Pello may be installed in a single room environment or as part of a two room suite. Excessive noise in the test environment, such as that produced by conversation, office equipment, or printers, reduces test validity because it tends to mask the test signals. - Page 12 Maximum Ambient Noise Test Tone Freq.

Page 66: Cleaning And Disinfecting Agents
Cleaning and Disinfecting Agents According to the recommendations from the CDC, audiometric equipment is considered to be non-critical medical equipment and typically requires cleansing followed by low to intermediate level disinfecting, depending on the nature of the contamination. Cleaning should be done with a mild soapy detergent (such as dishwashing liquid) and a damp cloth or an Endozime Sponge followed by an application of EPA-registered hospital disinfectant. -

ABLB In ABLB (Alternate Binaural Loudness Balance) test, the tone is presented alternately between the two ears. The level of the tone stays the same in one ear (i.e. fixed ear) and is varied up / down in the other ear (i.e. variable ear). The top section ABLB test display has common elements found on the previously described screens. - Page 72 • Select the ear to serve as the reference ear, typically the ear with the better hearing sensitivity. This ear will receive the tone at a fixed hearing level. • Select ABLB from the More Test Menu. • Set the level of the tone for each channel to 20 dB above the threshold of each corresponding ear.

Page 73: Sisi
The Navigation Menu has an option for the dB Step (continuous HL level) and an option for the SISI step (level increment). The results are not transferred to GSI Suite via the data transfer and therefore should be entered as a comment. - Page 74 Test Procedure - SISI (Short Increment Sensitivity Index) Test The SISI test is used to detect small level changes in a steady-state signal in patients with disorders of the cochlea. The SISI tests a patient’s ability to detect a 1 dB level change in a pure tone stimulus presented at 20 dB SL. A SISI consists of 20 target increments (200 msec at 1, 2, or 5 dB) presented every 5 seconds and can be completed for a number of frequencies.

Page 75: Ten Test
TEN Test The TEN test involves measuring the threshold for detecting a sinusoidal tone presented in a special background noise called “threshold-equalising noise” (TEN). The methods used to conduct the test are similar to those used for masking in conventional pure-tone audiometry, except that the signal threshold is measured in the presence of ipsilateral, continuous background noise and a 2-dB final step size is used to measure thresholds. - Page 76 Test Procedure - TEN Test Purpose of the TEN Test is to identify cochlear dead regions. This is useful for several purposes including the following: • Counseling about the benefit of hearing aids. • Assisting in hearing aid selection or cochlear implant candidacy. •...

Note: UT is the a.c. mains voltage prior to application of the test level. Guidance and Manufacturer’s Declaration - Electromagnetic Immunity The GSI Pello is intended for use in the electromagnetic environment specified below. The customer or the user of the Pello should assure that it is used in such an environment. - Page 117 To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the Pello is used exceeds the applicable RF compliance level above, the Pello should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the Pello.
