Review: Been using these to silence the neighbor's barking dog and they work great! - I hooked these up to an adjustable ultrasonic generator and 3D printed an enclosure. These two speakers are responsive to the ultrasonic sound generator and help us to quite down the neighbor's barking dog. They handle the volume and output just fine and have made it through spring rains and summer sun without issue.
Review: Very high pitched - Built a bark stopper with these

## Customer Reviews

### ⭐⭐⭐⭐⭐ Been using these to silence the neighbor's barking dog and they work great!
*by E***M on October 14, 2024*

I hooked these up to an adjustable ultrasonic generator and 3D printed an enclosure. These two speakers are responsive to the ultrasonic sound generator and help us to quite down the neighbor's barking dog. They handle the volume and output just fine and have made it through spring rains and summer sun without issue.

### ⭐⭐⭐⭐⭐ Very high pitched
*by J***N on September 22, 2025*

Built a bark stopper with these

### ⭐⭐⭐⭐⭐ These work great driven from Arduino as pest or animal repeller
*by Z***M on March 24, 2022*

These are loud at 5 volts. 4000hz made my ears hurt. They draw about 10ma so 2 can be hooked up to the tone pin on Arduino. Pest, animal repeller that you know that generates ultrasonic waves. Although I've seen these spec'd at 10v that much is not needed. Many repellers sold on line do not work or have insufficient volume. There is some sympathetic frequency generated at 31khz, but not bad to my old ears, but may bother others. *Edit 3/27/22 I added a 1k resistor in series to the + side of the speaker and it is now completely silent. Code : for variable frequency on Arduino 22khz to 42khz /* Varible Frequency Output From Godzilla */ int speaker = 9; /* Pin 9 */ unsigned int sfrequency = 22000; unsigned int efrequency =42000; void setup(){ pinMode(speaker, OUTPUT); } void loop(){ for (unsigned int i = sfrequency; i <= efrequency; i=i+500) { tone(speaker, i); delay(2000); /* 2 Seconds */ } }
