What’s the difference? One of the major differences between mobile phone radiation and WiFi is that mobile phone radiation is much more powerful. WiFi routers are generally much closer than mobile phone towers. So mobile phone radiation needs to be … Continue reading →

Temperature inversion is the reason why sounds can be heard much more clearly over longer distances at night than during the day—an effect often incorrectly attributed to the psychological result of nighttime quiet. What is the main reason why you … Continue reading →

Absorbers, as their name suggests, absorb a portion of the incident acoustic energy to reduce the amount being reflected back into the room, while diffusers scatter the sound energy over a wide angle, rather than allowing a coherent reflection to … Continue reading →

AAC files, in their original state, are much higher in quality than any of the other audio file formats on the list. . AAC files are generally similar in size to MP3s, despite being a tad higher in quality. They … Continue reading →

Not All Bats Echolocate Most bat echolocation occurs beyond the range of human hearing.Some bat sounds humans can hear. The squeaks and squawks that bats make in their roosts or which occur between females and their pups can be detected … Continue reading →

To display the command prompt, type echo on. If used in a batch file, echo on and echo off don’t affect the setting at the command prompt. To prevent echoing a particular command in a batch file, insert an @ … Continue reading →

The most common way to destroy wired headphones is by mistreating the cable. The real tragedy here is that the drivers inside the headphones are likely doing just fine—all they need is a cable to deliver the audio. But in … Continue reading →

Free Wi-Fi is unsafe. Free Wi-Fi networks, unlike paid Wi-Fi, do not require authorization to access. Free Wi-Fi is not private. Free Wi-Fi sacrifices productivity. Free Wi-Fi is often not there when you need it. With free Wi-Fi, you get … Continue reading →

Ultrasonic waves modulated with an audio signal are generated by ultrasonic transducers.So, the ultrasonic waves, and the sound coming from the directional speaker, spread very little and are confined to a narrow beam that can reach tens of meters. What … Continue reading →

“Wi-Fi networks are only as secure as the least secure device attached to them,” said IEEE member, Kayne McGladrey. Smart devices, like webcams, doorbells, switches, plugs, and other IoT devices are notoriously insecure. “Insecure IoT devices can be tricked into … Continue reading →

Echoes are created when sound waves hit an obstacle and bounce back. The smoother the obstacle the sound wave hits, the clearer and louder the echo – because the sound wave remains more intact when it hits a smooth surface … Continue reading →

Longitudinal waves show areas of compression and rarefaction : compressions are regions of high pressure due to particles being close together. rarefactions are regions of low pressure due to particles being spread further apart. What is the difference between refraction … Continue reading →

So both Bluetooth 4.2 and 5 can handle the highest quality wireless audio available, and with plenty of room to spare. This means that unless a higher-quality codec is developed, it doesn’t matter how much better or faster the Bluetooth … Continue reading →

Compared to Bluetooth 4.2, Bluetooth 5.0 can transmit eight times more data, at twice the speed, across four times the range.In short, it can transmit eight times more data, at twice the speed, across four times the range. Let’s look … Continue reading →

The accepted standard is that people should not be playing loud music (50 decibels or higher) between the hours of 11 p.m. and 7 a.m. Many feel that it is acceptable to push that to midnight or 1 a.m. on … Continue reading →
