Acoustic Immittance Meter
An Acoustic Immittance Meter is a device utilized to evaluate the status of the Tympanic membrane and middle ear. Varying amounts of positive and negative air pressure are introduced into the external auditory canal. During this process, compliance measurements are obtained and recorded resulting in a graphic representation of middle ear mobility. Acoustic reflex thresholds are also able to be obtained using an acoustic immittance meter.
Assisted Listening Device (ALD)
An Assistive listening device (ALD) is used to improve hearing ability for people in a variety of situations by amplification and better sound to noise ratio (SNR). A common usage is to aid people who are hard of hearing (HOH). The ALD may be used to help HOH people hear televisions and other audio devices and also to help people hear speech through public address (PA) systems such as in church or at a lecture.
The assistive listening device usually uses a microphone to capture an audio source near to its origin and broadcast it wirelessly over an FM (Frequency Modulation) transmission, IR (Infra Red) transmission, IL (Induction Loop) transmission, or other transmission method. The person who is listening may use an FM/IR/IL Receiver to tune into the signal and listen at his/her preferred volume.
The double wall audiometric exam suite is a sound treated room where audiometric evaluations are performed. There is an isolated acoustic floor in both the control room and exam room. The doors are acoustically sealed to provide a quiet environment for testing. The interior walls are constructed of perforated steel filled with sound absorbing material. A double glazed, laminated, safety glass window is located in the center of each room, for visual contact between patient and examiner.
Fun Fact: The human skeleton is composed of 300 bones at birth and by the time adulthood is reached, some bones have fused together to give a total of 206 bones in the body. Utilization of this is important during Anatomy and Physiology coursework.
Oral vibrators are oral motor products designed for muscle stimulation, strengthening, or desensitization. These tools can be used with individuals with autism, apraxia of speech, neurological deficits and/or stroke.
An otoscope is a hand-held device used for visual examination of the external auditory canal and tympanic membrane. An otoscope consists of a handle with power source (alkaline or rechargeable batteries), a magnifying lens, specula, and a small light bulb. It is designed to be operated by one hand, enabling the other hand to manipulate the patient's ear.
Passy Muir Speaking Valves
These Tracheostomy & Ventilator Swallowing and Speaking Valveare a simple medical device used by tracheostomy and ventilator patients. When placed on the hub of the tracheostomy tube or in-line with the ventilator circuit, the Passy-Muir Valve redirects air flow through the vocal folds, mouth and nose enabling voice and improved communication.
A Portable audiometer is a portable instrument used to measure hearing threshold levels when evaluating hearing sensitivity outside the sound treated room. Various frequencies and intensities are presented to each ear via supra aural earphones, insert earphones or bone oscillator. The patient responds by raising a hand or activating a response button to indicate the softest level at which they hear the signal.
The See-Scape detects nasal emission of air during speech and gives you an objective assessment of nasal emission immediately. See-scape gives an indication of air flow pressure rather than nasality but in so doing indicates a lack of velopharyngeal competence that is perceived as hypernasality. -Mayer Johnson
Speech Buddies are a set of revolutionary tools to help children overcome speech difficulties. By teaching correct tongue positioning for the five most difficult sounds – R, S, L, CH, and SH – children learn and feel how to correct a problem sound. Speech Buddies were designed by a team of expert speech-language pathologists and engineers from MIT & Columbia Universities.
A food and beverage thickener. Speech Language Pathologists can utilize this product to produce any desired consistency to assist with individuals with swallowing issues.
