Ultrasonic Emitter análises de aplicativos para 2 de dezembro

The highest frequency that the human ear is capable of perceiving is 20 KHz, although this frequency decreases with age. The speakers of mobile devices do not usually emit sound above 20 KHz, so this app is limited to 20 KHz. Most adults cannot hear above 15 KHz. Do not use with headphones. In case of discomfort, dizziness and other symptoms stop use immediately! Do not use this application as a weapon against dangerous animals. The application is used at your own risk. The developer bears no responsibility for the use of this application. Some uses of high frequency sounds: - Hearing tests. This tool can be used to perform hearing tests, although accuracy may vary depending on the device used. The app can generate high-frequency tones in a specific range, usually above a person's normal hearing range. These tones are of different frequencies to evaluate different parts of the hearing spectrum. To assess hearing threshold, users can adjust the intensity of the sound emitted by the app until they no longer hear the tone. This point, known as the hearing threshold, can indicate the minimum detectable frequency for the individual. It is important to note that a hearing test app based on high-frequency sounds cannot completely replace a professional hearing evaluation by a hearing health specialist. However, it can serve as an initial tool for self-assessment and hearing monitoring, providing preliminary information about hearing health. - Pet training. Applications designed for training dogs and cats can emit high-frequency sounds that are striking or uncomfortable for animals, which can be used to teach them certain behaviors or to correct unwanted habits. High frequency sounds can be used as positive or negative reinforcement during the training process. For example, a pleasant sound could be associated with a desired action to positively reinforce the behavior, while an unpleasant sound could be used as negative reinforcement to deter unwanted behaviors. High-frequency sounds can be used to teach basic obedience commands, such as sit, stay, or respond to the owner's call. The association between the sound and the desired action can speed up the learning process. This application can be used similar to a high frequency whistle. If you notice a sign that the dog or cat being trained feels a strong repulsion towards the high-frequency sound, you should stop using it immediately. The concept of using animal nuisance frequencies as a repellent method has been the subject of research and debate. It has been suggested that some animals, such as rats, mice and other rodents, as well as mosquitoes and other insects, may be sensitive to certain sound frequencies that are outside the human auditory range, and that these sounds may serve as a repellent to such animals. Despite the popularity of the idea, it is unproven. The effectiveness of high frequency sounds as repellents is not supported by scientific research. This app is not an effective solution as an anti-rat or anti-mouse tool and is not effective as an ultrasonic barrier for these purposes. The purpose of this app is not to scare away animal pests.
