Condominium residing has its ups and downs, with the downs typically profitable out. Residing in shut proximity to maybe dozens of different folks, every with totally different schedules, tastes, and concepts about what constitutes acceptable conduct nearly inevitably results in clashes and compromises. Noise, particularly, turns into a continuing difficulty, whether or not it’s the neighbor’s late-night events, the incessant barking of a close-by canine, or the cacophony of footsteps echoing by way of skinny partitions. Privateness seems like a luxurious as each sound, from conversations to the opening and shutting of doorways, infiltrates one’s residing area.
One notably annoying downside had been pestering engineer and machine studying fanatic Roni Bandini — a neighbor that blasted reggaeton music each morning with the regularity of Previous Trustworthy. Bandini notes that he doesn’t have something in opposition to reggaeton music per se, however when it makes the partitions vibrate on daily basis at 9 within the morning, it shortly will get outdated. Most condo dwellers would both grin and bear it, or get out their trusty outdated noise-canceling broom to bang on the ceiling. However being a member of the Hackster neighborhood, Bandini selected to take a extra fascinating method.

After considering lengthy and exhausting — and doubtless contemplating many methods involving sharks, lasers, and sharks with lasers — Bandini in the end settled on the thought of constructing a tool referred to as Reggaeton Be Gone. This system leverages machine studying to hear for the precise sound of reggaeton music, then it sends jamming alerts to intervene with close by Bluetooth audio system which might be taking part in the offending music.
The Reggaeton Be Gone is powered by a Raspberry Pi 3 single-board laptop, which has enough computational horsepower to run an audio classification neural community, and likewise comes geared up with a Bluetooth transceiver. A USB microphone was additionally added to the construct to seize audio. Bandini completed off the system by 3D printing a slick case with a 128 x 32 pixel OLED show, as a result of if you’re going to foil the neighbor’s annoying plans, you need to do it with fashion.
A machine studying classifier was wanted that would detect the precise patterns which might be attribute of reggaeton music. Since no pre-trained fashions may very well be discovered by Bandini for the sort of music, he collected some audio samples (which the neighbor was freely providing), and uploaded them to Edge Impulse the place a neural community classifier might simply be educated and deployed to the Raspberry Pi.

Utilizing this classifier, the Reggaeton Be Gone regularly captures audio samples and checks to see in the event that they sound like reggaeton music. If a predefined certainty threshold is exceeded, a Python program jumps into motion. It’ll ship a stream of requests to close by Bluetooth audio system to intervene with their operation. The objective is to both take them offline, or make the audio high quality so poor that there isn’t any selection however to show the music off.
Tons extra particulars can be found within the venture write-up in case you have an annoying neighbor of your personal to cope with. You will need to notice, nonetheless, that jamming Bluetooth units might not be authorized the place you reside, so make sure to verify native legal guidelines earlier than you determine to get rid of reggaeton from your personal environment.
