The W2-LFS-630 low frequency sounder from FireAngel is designed for use in conjunction with a wirelessly interconnected Wi-Safe 2 smoke and heat alarm system.
Sound is a pressure wave and is the result of molecules impacting upon each other, caused for example by objects hitting each other (such as a hammer onto an anvil) or from objects vibrating (such as our vocal chords). Many decades ago hearing tests were carried out on several hundred young adults with anatomically healthy ears by measuring the faintest level of puretone signal each could hear, measured in dBSPL. Note 2: As shown in the graph above, young adults with healthy ears can typically hear between 20Hz (very low pitch) to 20,000Hz (very high pitch), but as we grow older this range narrows, especially from the high frequency end. It would be quite confusing to use a graph like this to base every other test upon, so a flat graph called an Audiogram was produced (shown below). A typical test result is shown below, on an Audiogram which also shows where typical speech sounds occur. This audiogram shows a client with good low frequency hearing and mild to moderate high frequency hearing loss.
The circle on the left shows that the client is hearing louder vowels sounds normally, but the circle on the right shows they are missing the quieter consonant sounds, which are needed for clarity of speech.

The research, which was presented at the American Thoracic Society’s 2014 International Conference, found that of the 13,967 participants sampled, about 10 percent had at least moderate sleep apnea.

The above audiogram represents the hearing of an individual with normal hearing in the low frequencies (pitch) sloping to a severe high frequency hearing loss in the left ear and a moderate to severe hearing loss in the right ear.
The sounder provides additional audible warning to wake high risk occupants including children, those under the influence of alcohol and people with moderate hearing loss.
Sound therefore requires a molecular medium to pass through, and the sound is heard until the energy fades out (this fade through air is halved every doubling of distance and is known as the inverse square law).
This then gave an average minimum threshold of hearing for people with good hearing in which to measure other people against. Hearing tests are typically limited between 250Hz-8000Hz being that this is the range of speech.


This client will therefore perceive that people are not speaking clearly – a clear sign of early stage hearing loss. These patients had a 31 percent increased risk of high frequency hearing impairment, a 90 percent increased risk of low frequency hearing impairment and a 38 percent increased risk in combined high and low frequency hearing impairment after controlling for other causes of hearing loss and potentially confounding factors like age and sex. Neomi Shah, an associate director of the pulmonary sleep lab at Montefiore Medical Center in New York City. Chopra also noted that “the mechanisms underlying this relationship merit further exploration. Mains powered with a back-up battery that continues to power the unit after a mains failure, the sounder can be wirelessly interlinked with up to 50 Wi-Safe 2 devices. The graph also shows the average upper threshold of hearing where sounds are considered uncomfortable (but not painful) – which is on average 120dBHL.
