ALL ABOUT Smoke detectors

A device that senses smoke, typically as an indicator of fire. Commercial smoke detectors issue a signal to a fire alarm control panel as part of a fire alarm system, while household smoke detectors issue an audible/visual alarm from the detector itself

History
The first automatic electric fire alarm was patented in 1890 by Francis Robbins Upton, George Andrew Darby patented the first European electrical heat detector in 1902. In the late 1930s Swiss physicist Walter Jaeger tried to invent a sensor for poison gas he's experiment paved the way for the modern smoke detector.

Types

The two main types of smoke detectors on the market include ionization detectors and photoelectric detectors.
Ionization - Inside there’s an ionization chamber with a small amount of radiation particles bouncing around. When smoke enters the chambers, the signal gets interrupted, causing the alarm to trigger.
Photoelectric - These alarms contain light-emitting diodes that send a beam of light across a chamber, a sensor detects light, when smoke enters the chamber, it obstructs the light witch causes the alarm to trigger.

Why use one?
When smoke alarms were present it prevented, 73% of possible deaths & 82 % of possible injuries.
The risk of dying in reported home structure fires is 55 % lower in homes with working smoke alarms

ALL ABOUT Frequencies

Sound/audio frequency is the speed of the sound’s vibration which determines the pitch of the sound and how it travels through the air.

How do you measure Frequency?
The number of sound vibrations counted per second is called the frequency. The frequency of the waves will be measured in hertz (Hz), this reflects the amount of cycles per second.

Low frequency
Also called infrasound, low-frequency sounds are sound waves with a frequency below the lower limit of audibility, between 20 Hz and 500 Hz.

Middle-frequency
Middle-frequency sounds are sounds that are between the 500 and 2000 Hz range, which is where you can intelligently determine human speech. Sounds in this range often have a tinny or horn-like quality.

High-frequency
High-frequency sounds starts at above 2000 Hz, at this level, the sound gives “presence” to speech, speech sounds more authentic. At 10,000 Hz, you’ll hearing sounds like crashing cymbals and chirping birds.
