![]() ![]() Remove all such connected devices and if the noise stops, you can rest assured that the TV is alright and the noise is not coming from it. If you find that after muting the TV speaker the noise continues, then it could be due to any other device you may have connected to the TV. If the noise continues, then it could be due to other external interference. If the noise has stopped, the speaker could be the culprit. If you want to be sure that the speakers of your television are not the reason for the noise, press the mute button on the TV remote. If any of these are loosely connected or inserted into the wrong port on your TV, then it can create some noise. You may have connected some devices to your TV using cables, such as external speakers, a DVD player, or other audio-video equipment. There could be a genuine issue with the TV that calls for a repair.If any defective device is connected to the TV, you may hear a strange noise.There could be broadcasting issues with the program you are watching.The noise could be from the TV speakers.Noise distortion can occur if the cables connected to the TV’s different ports are not properly plugged in or if they are damaged.There may be other reasons why your TV may be making weird noises, like buzzing or beeping. These noises need not be a cause of concern. When the TV is turned ON, they tend to expand slightly due to the heat. The material of construction of these components could be metal or plastic. “This study suggests that we might literally see such negative events.The weird noises you hear from your TV after you switch it OFF may be due to some of the internal components’ thermal contraction. For example, if you have a tooth removed, can you literally feel the absence of the tooth?” Prof Phillips said. “Interesting questions arise in other senses too. He added that the findings open the door to investigating whether other abstract concepts can be experienced directly by people.įor example, can humans actually see holes or empty space and can people “see” darkness or shadows. “We think this similarity is sufficient to justify the claim that we really do hear the silence.” “We do think that the brain interprets the lack of sound in a similar way to the way it interprets sound itself, namely that it segments the period of silence and treats it as a discrete event. Prof Ian Phillips, study co-author at the Johns Hopkins University, told The Telegraph: “We do think that subjects in our experiments really heard the silence as a silence (i.e., as the absence of sound), and not as a sound (and that they know this). They add: “Our results suggest that silence is truly heard, not merely inferred, introducing a general approach for studying the perception of absence.” ‘Interesting questions arise’ “This long-standing question remains controversial in both the philosophy and science of perception, with prominent theories holding that sounds are the only objects of auditory experience and thus that our encounter with silence is cognitive, not perceptual.” “In these cases, do we positively hear silence? Or do we just fail to hear, and merely judge or infer that it is silent? ![]() ![]() “However, daily life also seems to present us with experiences characterised by the absence of sound – a moment of silence, a gap between thunderclaps, the hush after a musical performance. “Auditory perception is traditionally conceived as the perception of sounds – a friend’s voice, a clap of thunder, a minor chord,” the scientists write in their study published in the Proceedings of the National Academy of Sciences. The brain worked in exactly the same way in this variant of the original study, the team found, indicating that silence and sound are heard in the same way. ![]() This well known illusion sees the mind tricked into thinking the one beep is longer than the two consecutive sounds despite them being the same.Īcademics from Johns Hopkins carried out this experiment but replaced the bleeps with short bouts of silence. One task involved producing two beeps and one long beep which totalled the same length of time. The team ran auditory illusions to unpick if a person was perceiving silence owing to a lack of sound or could actually hear silence itself. The latest study is the first to add empirical evidence to the debate over whether humans can hear silence and it suggests that the firing of the auditory neurons in the brain can be triggered by silence even if the sound-induced vibrations are not present in the ear.Ī team of psychologists and philosophers devised an experiment with 1,000 volunteers who took part in seven listening tasks. ![]()
