@Alfred What would it take, technology wise , to create highly effective noise canceling headphones for dogs?

@artemis 1. High-quality noise-cancelling technology: Noise-cancelling technology in headphones typically works by actively listening to ambient sound and producing an opposing waveform that cancels out the sound. This technology would need to be tailored for the range of frequencies typically audible to dogs. 2. Specialised materials: To accommodate the varying shape and size of a dog’s head, it would be necessary to create specialised materials that can comfortably fit on a wide range of canine ears and heads. Additionally, waterproofing and sweat-resistant materials would be needed to protect the device from damage caused by exposure to water and saliva. 3. Adaptive volume control: It would be beneficial to incorporate adaptive volume control

@Alfred What frequencies are used for noise cancelling devices for humans?

@artemis Noise-cancelling technology used in headphones for humans typically works by listening to ambient sound and producing an opposing waveform that cancels out specific frequencies within a certain range. This range usually includes low frequency ranges such as bass or background noises like air conditioners or traffic noise. Additionally, higher frequency ranges such as voices or alarms can also be filtered out.

@Alfred Can you be more specific about the frequency ranges?

@artemis Noise-cancelling technology used in headphones for humans typically works by listening to ambient sound and producing an opposing waveform that cancels out specific frequencies within a range of 20 Hz – 20 kHz. Within this range, low frequency ranges such as bass (20 Hz – 250 Hz) or background noise (250 Hz – 2 kHz) like air conditioners or traffic noise are filtered out. Additionally, higher frequency ranges such as voices (2 kHz – 4 kHz) and alarms (4 kHz-20 kHz) can also be filtered out.

@Alfred What are the frequencies perceived by dogs?

@artemis Dogs can typically perceive sound in a frequency range of 40 Hz – 60 kHz. This range includes bass frequencies (40 Hz – 250 Hz), lower mid-range frequencies (250 Hz – 1 kHz), and higher mid-range and treble frequencies (1 kHz – 20 kHz). They are also able to detect ultrasonic frequencies (20 kHz – 60 kHz) that are beyond the range of human hearing.
