“…While complaints about noise in restaurants and bars would appear to have been on the rise in the west in recent years (e.g., Belluz, 2018;Moir, 2015; see Spence, 2014a, for a review), it is worth noting that researchers have actually been commenting on overly loud restaurants for many decades now (see Pettit, 1958, for an early example). The research that has been published to date shows that loud background noise, regardless of whether it is airplane noise, white noise, or even the background noise of a restaurant, or bar, affects both the perceived taste of food and drink, as well as people's ability to discriminate various aspects of their tasting experience (Rahne, Köppke, Nehring, Plontke, & Fischer, 2018;Trautmann, Meier-Dinkel, Gertheiss, & Mörlein, 2017; see Spence, 2014a, for a review).…”

Food product-extrinsic sounds (i.e., those auditory stimuli that are not linked directly to a food or beverage product, or its packaging) have been shown to exert a significant influence over various aspects of food perception and consumer behaviour, often operating outside of conscious awareness. In this review, we summarise the latest evidence concerning the various ways in which what we hear can influence what we taste. According to one line of empirical research, background noise interferes with tasting, due to attentional distraction. A separate body of marketing-relevant research demonstrates that music can be used to bias consumers’ food perception, judgments, and purchasing/consumption behaviour in various ways. Some of these effects appear to be driven by the arousal elicited by loud music as well as the entrainment of people’s behaviour to the musical beat. However, semantic priming effects linked to the type and style of music are also relevant. Another route by which music influences food perception comes from the observation that our liking/preference for the music that we happen to be listening to carries over to influence our hedonic judgments of what we are tasting. A final route by which hearing influences tasting relates to the emerging field of ‘sonic seasoning’. A developing body of research now demonstrates that people often rate tasting experiences differently when listening to soundtracks that have been designed to be (or are chosen because they are) congruent with specific flavour experiences (e.g., when compared to when listening to other soundtracks, or else when tasting in silence). Taken together, such results lead to the growing realization that the crossmodal influences of music and noise on food perception and consumer behaviour may have some important if, as yet, unrecognized implications for public health.

“…Intriguingly, however, white noise impaired participants' sensitivity for detecting sour and enhanced sweet taste ratings, while having no effect on the perception of bitter or salty tastants. Furthermore, Rahne et al (2018) reported no effects on olfactory detection thresholds. It should be noted that the n-butanol used in these experiments is not a food odor and these nonfood odors may be perceived differently (Albrecht et al, 2009).…”

“…(2011) reported higher taste and odor thresholds at low atmospheric pressure and noise compared to subsequently applied normal pressure. Rahne, Köppke, Nehring, Plontke, and Fischer (2018) have also recently published research in the area of background noise. They assessed both taste (gustatory) and orthonasal olfactory detection thresholds as a function of varying ambient noise (present vs. absent) and atmosphere (normal vs. hypobaric).…”

The intention to send a crewed mission to Mars involves a huge amount of planning to ensure a safe and successful mission. Providing adequate amounts of food for the crew is a major task, but 20 years of feeding astronauts on the International Space Station (ISS) have resulted in a good knowledge base. A crucial observation from the ISS is that astronauts typically consume only 80% of their daily calorie requirements when in space. This is despite daily exercise regimes that keep energy usage at very similar levels to those found on Earth. This calorie deficit seems to have little effect on astronauts who spend up to 12 months on the ISS, but given that a mission to Mars would take 30 to 36 months to complete, there is concern that a calorie deficit over this period may lead to adverse effects in crew members. The key question is why astronauts undereat when they have a supply of food designed to fully deliver their nutritional needs. This review focuses on evidence from astronauts that foods taste different in space, compared to on Earth. The underlying hypothesis is that conditions in space may change the perceived flavor of the food, and this flavor change may, in turn, lead to underconsumption by astronauts. The key areas investigated in this review for their potential impact on food intake are the effects of food shelf life, physiological changes, noise, air and water quality on the perception of food flavor, as well as the link between food flavor and food intake.

“…However, pressure could have influenced the separate taste modalities, like 'salty'. Rahne et al [18] reported that hypobaric pressure significantly reduced the scores for 'sour' and 'salty' compared to the scores for 'sweet' and 'bitter'. O'Reilly et al [10] found an increase in 'sweet' sensitivity and a decline in 'sour' sensitivity after a 17-day dive.…”

Introduction Taste and smell are important for occupational performance and quality of life. Previous studies suggested that the function of these senses might be influenced by ambient pressure and noise. This knowledge would be helpful for divers, submarine crews, or mine workers. The present study aimed to investigate the effects of noise and hyperbaric pressure on olfactory and gustatory functions. Methods This prospective controlled study included 16 healthy male divers. Inside a hyperbaric chamber, participants performed olfactory and gustatory function tests at sea level pressure and at 2 bar pressure. The olfaction threshold, and the discrimination and identification of odorants were measured with validated´Sniffin sticks´. Taste identification and the gustation threshold scores were examined with validated filter paper strips. Tests were performed under two conditions: noise reduction (silence) and white noise stimulation presented at 70 dB sound pressure level. Results The results showed that normobaric and hyperbaric ambient pressures did not significantly affect olfactory or gustatory function. Moreover, noise had no relevant impact on taste or odor sensation. The odor identification score was not influenced in hyperbaric conditions, and the odor threshold score was not influenced by ambient noise or both barometric conditions. The only taste modality affected by hyperbaric conditions was the sensitivity to salty taste, but it was not significant.
