These figures show alarms are still an important means to assist in awakening, and given the 24-hour society in which we live and work, the need for peak performance from our waking device, the stimuli they produce, and the audio we select, is advantageous to counteract the negative effects of SI. YouGov report that out of 586 participants surveyed, 68.2% use a form of alarm for waking, of these, 23% use an alarm clock, 14.9% a clock radio, and 26.3% an alarm on a cell phone. There has been growing research interest into the mechanics and architecture of SI, however the modalities and means to activate waking remains in its early stages with respect to this issue. The poor decisions made after napping were attributed to the disaster, and have been linked to the effects of SI. It has been shown that the captain of the aircraft had recently woken from an in-flight nap just prior to the crash. This has been highlighted as a likely factor in the 2010 Air India Express air crash disaster that resulted in 158 fatalities. Initiated upon waking, SI’s symptoms can last for seconds, minutes or hours, where extended SI may impact human performance in a variety of situations and occupations. Sleep inertia ( SI) is a transitional sleep-wake phenomenon characterized by low arousal and reduced cognition. NASA astronaut journal report during orbit aboard the International Space Station. My body apparently went on strike for better working conditions.” I slept through two alarms, one set for 0600 and another a half-hour later to remind me to take some CEO pictures. Considering that the implementation of auditory assisted awakening is a common occurrence, the musical elements of a chosen waking sound may be an area to further interrogate with respect to counteracting sleep inertia. Together these findings raise questions regarding the impact melody and rhythm may hold with respect to sleep inertia intensity. Additionally, our secondary analysis revealed that a sound rated as melodic is considered to be more rhythmic than a melodically neutral interpretation. However, the analysis did reveal that a sound which is ranked as melodic by participants shows a significant relationship to reports of reductions in perceived sleep inertia, and in contrast, sound rated as neutral (neither unmelodic nor melodic) returns a significant relationship to the reports of increases in perceived sleep inertia. Our results did not return any significant association between sleep inertia and the reported waking sound type, nor the subject’s feeling towards their sound. This data enabled the analysis and comparison between these responses to identify statistically significant relationships. Through an anonymous, self-report online questionnaire, fifty participants ( N = 50) reported attributes of their preferred waking sound, their feeling towards the waking sound, and perceived sleep inertia after waking. The goal of this research is to understand how a particular sound or music chosen to assist waking may counteract sleep inertia, and more specifically, what elements of these sounds may contribute to its reduction. The type of sound people set as their alarm for waking has been shown to reduce the effects of sleep inertia, however, the elemental musical factors that underpin these waking sounds and their relationships remain unclear. You can define your own CSS or modify it in order to customize the alarm clock according to your needs.Sleep inertia is a potentially dangerous reduction in human alertness and occurs 0–4 hours after waking. Now, style the clock using the following CSS styles. So, the complete HTML structure for the clock and alarm settings is as follows: ģ. Likewise, create two buttons for a snooze and set an alarm. Similarly, create the select elements for hours, minutes, seconds, and AM/PM for alarm settings. After that, create a div element with a class name “clock-wrapper” and place the h2 heading element with a class name “clock” inside it. First of all, load the Normalize CSS and Orbitron (digital clock fonts) CSS into the head tag of your webpage. How to Create JavaScript Alarm Clock with Soundġ. Similarly, it can also be used in quiz app with timer or limited-time offers to alert the users with sound. You can integrate this alarm code snippet in your project as a reminder or allow users to set an alarm for a certain time. Users can easily set an alarm for a certain time, when the alarm starts, the user can turn it off or snooze for the next five minutes. It comes with a digital clock that shows the current time and alarm settings interface. This JavaScript code snippet helps you to create an alarm clock with sound.
