what ICs can u suggest to be used in my sound level meter for outdoor speakers in order to have an accurate measurements. power amplifier to be used will be 50, 70, 100 watts power out put.
zafranax said:my thesis proposal will be a sound level indicator for loudspeaker using LEDs. this will be a bar graph display that will indicate the level of the sound of a certain loudspeaker.what ideas can u share about my thesis proposal?
An outdoor speaker sound level meter is a device used to measure the sound level or intensity of sound produced by outdoor speakers. It typically consists of a microphone, amplifier, and display screen.
It is important to have a sound level meter for outdoor speakers to ensure that the sound level is not too loud and potentially harmful to human hearing. It can also help to prevent noise complaints from neighbors and ensure compliance with local noise regulations.
Some suggested ICs for outdoor speaker sound level meter include the LM3915, LM3916, and LM3914. These are all voltage level indicator ICs that can be used for audio applications such as sound level meters.
These ICs work by converting the input sound level signal into a corresponding voltage level, which is then displayed on the LED bar graph. The LM3915 and LM3916 have 10 LED outputs, while the LM3914 has 20 LED outputs, allowing for more precise measurement of sound levels.
Yes, there are alternative options such as using a microcontroller or a dedicated sound level meter chip. However, using ICs offers a simple and cost-effective solution for measuring sound levels in outdoor speaker systems.
